Ultrasonic measurement flowIQ® 3101 measures cold water consumption in multi-unit and com-mercial buildings.

Ultrasonic flow measurement guarantees pinpoint accuracy and longevity. Ultrasonic flow measure-ment is based on the transit time method and all measurements, references, readings, calculations and data communication are controlled by an advanced, specially designed, electronic circuit. Thus, the meter has no moving parts, which makes flowIQ® 3101 resistant to wear and impurities in the water.

Long rangeTo meet increasing market demands for smart metering flow IQ® 3100 comes with the newest radio tech-nology, including integrated 915 Mhz band RF which complies with Part 15 of the FCC Rules and enables remote reading of consump-tion data. Consumption data can also

be read manually directly from the display or by an optical eye.

The long range antenna transmits high-power radio signal with intelli-gent coding - which can be read from a long distance with ‘drive-by’.

Leak detectionflowIQ® 3101 includes leak detection. This means that the utility and the consumer can quickly discover and repair costly leaks while avoiding further water loss.

Construction The meter is hermetically closed and vacuum-sealed to prevent humidity from reaching the electronics and avoid condensation between the glass and display. The meter is IP68 (submersible) type tested and suit-able for installation in meter pits.

An internal lithium battery, powers the meter and guarantees the me-ter’s total longevity.

Lead-free and certified to NSF/ANSI61 The meter housing is made of plastic material polyphenylene sulfide (PPS) and is mounted on a measuring part made of stainless steel. The meter can be installed vertically or horizon-tally and quickly mounted independ-ent of existing piping and installation conditions.

The unique combination of flowIQ® 3101 features reduces cur-rent operating costs to measure wa-ter usage and minimizes unexpected expenses in connection with possible leakage.

General description

flowIQ® 3101 is a series of integrated water meters intended for consumption and distribution measurement of cold residential water in large multi-unit and commercial buildings. The meter fits perfectly into a network of flowIQ® 2100 household meters.

flowIQ® 3101 is a static water meter based on the ultrasonic principle. The water meter has been developed on the basis of Kamstrup’s experience since 1991 with the development and production of static ultrasonic meters.

This technology has many advantages, including no moving parts so the meter is unaffected by parti-cles in the water and measures consistently throughout its lifetime.

flowIQ® 3101 has been subjected to a comprehensive set of tests to meet AWWA standards and is certified to NSF/ANSI61.

flowIQ® 3101 is constructed as a vacuum chamber of molded composite material, which is mounted on a measuring tube of stainless steel. Thus, the electronics are fully protected against penetration of water, both from medium pipes and the environment. The meter is IP68 rated for submersible envi-ronments. Hence, the meter is specially suited for small pump stations and distribution wells, as well as meter pits, which are frequently filled with water.

The volume is measured using bidirectional ultrasonic technique based on the transit time method, proven a long-term stable and accurate measuring principle. Two ultrasonic transducers send sound signals with and against the flow, respectively. The ultrasonic signal traveling with the flow reaches the opposite transducer first. The time difference, between the two signals, can be converted into flow velocity and thereby the volumetric flow rate can be calculated.

The accumulated water consumption is displayed by flowIQ® 3101 in gallons, or cubic feet with nine digits and up to three decimals. The display has been specially designed to obtain long lifetime and sharp contrast in a wide temperature range.

In addition to volume reading, a number of information codes are displayed. The meter also measures ambient temperature continuously, storing minimum, mean and maximum temperatures daily.

All registers are saved daily in the meter memory for 460 days. Monthly data for the latest 36 months are also saved.

flowIQ® 3101 comes with integrated 915MHz band RF radio

flowIQ® 3101 is fitted with an optical eye, which makes it possible to read consumption data and information codes, stored in the meter’s data logger. The optical eye gives access to configure the meter.

The water meter is powered by an internal lithium battery.

Placement in prolonged direct sunlight must be avoided.

The meter can and may only be opened by Kamstrup Headquarters. If the meter has been opened, and the sealing has thus been broken, the meter is no longer valid for billing purposes. Furthermore, the factory waranty no longer applies.

Measurement of temperatures

Temperature monitoringflowIQ® 3101 measures the ambient temperature. The measurements can be used to monitor the installation and to provide an indication of the ambient conditions.

Temperatures are logged in the daily and monthly records.

Minimum, mean and maximum values are logged daily. The register contains the last 460 days.

On the first day of each month the minimum, maximum and average temperatures, recorded in the past month, are stored in the register. The register stores the last 36 months of values.

Temperature values are referred to in Fahrenheit and can be read via the optical eye and send by the Wireless M-Bus radio signal. Optional temperature combinations in the radio package are described in the section ’Optional data in data logger’.

Ambient temperaturesMonitoring the ambient temperature of the installation can be used as a warning of freezing temperatures or unintended high temperatures. The measurement in the meter housing corresponds to the ambient temperature where the meter is installed.

The temperature is measured every minute. The maximum and minimum values are calculated based on a 2 minutes averaging value. The average temperature is a time-weighted mean value.

Consumption valuesBesides readout of the current total registered water use the meter saves a number of other consumption data.

Following values can be send via the Wireless M-Bus radio signal:

· Target Volume - ie meter reading the first day of the month

· Maximum flow - daily

· Maximum flow - monthly

· Selected values of ambient temperature.

Display and information codes

flowIQ® 3101 can be read from the large, easily readable, specially designed display. Nine large fig-ures indicate gallons or cubic feet. The last three figures may indicate decimals.

The information codes in the display have the following meaning and function:

Info code flashes in the display

Meaning

FLOW Indicates water flow through the meter. If there is no flow, the text will be off. This text is not flashing

LEAK The water has not been stagnant in the meter during the last few days.This can be a sign of a leaky tap or toilet.

BURST The water flow has exceeded a preprogrammed limit for a minimum of 30 minutes which is a sign of a burst pipe.

TAMPER Attempt of fraud. The meter is no longer valid for billing.

Gal / ft3 / m³ Consumption is indicated in gallons, cubic feet or cubic meters

VERIFIC Will always be off when the meter is in operation - text will be on during factory control and verification of the meter.

DRY The meter is not water-filled. In this case nothing will be measured.

REVERSE The water flows through the meter in the wrong direction.

RADIO OFF The meter is still in transport mode with the built-in radio transmitter turned off. The transmitter turns on automatically when the first quarter gallon of water has run through the meter.

Squared ‘dot’ One small square flashing indicates that the meter is active.

‘A’ followed by a number Change log

Indicates the number of metrologic changes the meter has gone through after factory verification. If no adjustments have been made both the A symbol and the digit are inactive

Information codes ‘LEAK’, ‘BURST’, ‘DRY’ and ‘REVERSE’ switch off automatically when the conditions that activated them no longer exist. In other words, ‘LEAK’ disappears when the water is stagnant; ‘BURST’ disappears when the consumption falls to normal level; ‘REVERSE’ disappears when the water no longer flows in the wrong direction; ‘DRY’ disappears when the meter is filled with water.


1158101228_D1_US_12.2014

Data registers

flowIQ® 3101 has a permanent memory (EEPROM), in which the values of various data loggers are saved.

The meter includes the following registers:

Data logging interval Data logging depth Logged value

Monthly logger 36 months See table below

Daily logger 460 days See table below

Info logger 50 events Info code, meter reading and date

Thus, it is always possible to read target volume and information codes for each of the latest 36 months as well as corresponding meter reading and possible information codes for each of the latest 460 days. The loggers can only be read via the meter's optical eye.

The monthly logger is written on the first day of the month, the daily logger is written at midnight. The following registers are logged:

Every time the information code changes, date and information codes are logged. Thus, it is possible to read the latest 50 changes of the information code as well as the date the change took place. Read-ing is only possible via the optical eye.

915MHz band RF– wireless radio communication

flowIQ® 3101 communicates via a high-power antenna and integrated 915MHz band RF, which gives access to easy and fast wireless reading of the meter.

The integrated 915MHz band RF transmits a data package every 16 seconds. In order to obtain long battery lifetime, the data package has been compressed and includes only the most important meter readings.

By connecting Kamstrup USB Meter Reader to an antenna on the roof of the car, the meter can be read via ‘drive-by’.

The following details are transmitted:

• Current meter reading

• Optional register combination of:

Target volume – monthly / max. flow / ambient temperature

• List of active information codes

• List of information codes which have been active within the latest 30 days

The list of information codes, which have been active, also includes information on how long they have been active.

915MHz band RF is an open standard, following en13757-4 : 2010, which means that while the flowIQ® 3101 can be configured with or with-out encryption of the transmitted signal, encryption is required in the United States.

Encryption protects personal data against unauthorized monitoring. Furthermore, the encryption file provides easy access to import meter data for reading programs.

flowIQ® 3101 can now also be read by using for example the ’READy’ – Kamstrup’s mobile app – which is ideal for ’walk-by’ and ’drive-by’ reading.

Below is a screen shot of how a reading may appear on the user’s smart phone.

Pressure loss

According to AWWA standards the maximum pressure loss must not exceed 15 PSI at safe maximum operating capasity. The pressure loss in a meter increases with the square of the flow and can be stated as:

Q=kv x √∆p

where:

Q = volume flow rate GPM

kv = volume flow rate at 1PSI pressure loss

∆p = pressure loss PSI
