Actaris manufacture an extensive range of

industrial gas meters in their factories in the

UK and Germany. The range encompasses

Diaphragm, RPD and Turbine technologies.

Actaris’ extensive experience and breadth of

technology allows users to select the most

suitable meter for a specific task, secure in

the knowledge that they are selecting from

meters whose performance is second to

none.

The site at Stretford, Manchester, has been

famous for the manufacture of high quality

diaphragm meters for many years, and the

“U” series meters are highly regarded

technically around the world.

Karlsruhe has equal fame for it’s “Rombach”

Diaphragm and Turbine meters, and is fast

growing a strong reputation for developing

the Delta RPD meters into a globally

recognised range.

Diaphragm Meters

“Delta” RPD Meters

“Fluxi” 2000 TZ Turbine Meters

The “U” Series of diaphragm meters cover

flow rates from 0.04m /h to 160m /h.

Diaphragm meter technology gives long life,

accuracy and the ability to register very small

gas flows.

The Delta range of RPD meters can register

flow rates from 0.5m /h to 1000m /h.

Compact design with flexible measurement

performance over a wide range of loads

make these a popular “general purpose”

meter.

The Fluxi turbine meters are a low cost high

accuracy range and can be used in specific

installations for metering up to 6500m /h of

gas. These are primarily used for

applications where flow is constant or varying

within a range down to 1/20 of the

maximum flow rate.

Diaphragm MetersThe “U” Series of diaphragm meters cover flow

rates from 0.04m³/h to160m³/h. Diaphragm

meter technology gives long life, accuracy and

the ability to register very small gas flows. The

high performance of the modern Diaphragm

meter is due to a combination of the use of

proven materials technology, a stable design,

and diligence in manufacturing.

Fixed stroke measurement units lead to

enhanced measurement stability and accuracy.

This allows all calibration to be performed in

the index.

Modern materials and the latest moulding and

machining techniques mean that there is no

Fixed stroke measuring units

requirement for lubrication during the meters

normal operating life. In fact, there is no

routine maintenance requirement for the U

series meters.

A strong partnership with our suppliers means

that Diaphragms are manufactured to a

specification unique to UK requirements.

These diaphragms are designed to operate for

extended periods while exposed to the worst

that the gas network can deliver.

Radial valves constructed from low friction

materials give the U series exceptional low flow

accuracy, and deliver low pressure drop across

the whole flow range.

RPD Meters

The Delta range of RPD meters can register

flow rates from 0.5m³/h to1000m³/h. The

compact design and flexible measurement

performance over a wide range of load types

makes these a popular “general purpose”

meter. Meters are factory set for up, down,

left-to right or right-to-left flow direction, and

must be installed horizontally. Delta meters are

relatively insensitive to flow conditions, and can

be installed in small spaces with bends and

other features nearby in the pipework. The

use of a flexible connector is recommended in

installations with low metering pressure.

The MRA25A and MRA40A are the metric

successors to the recognised D0.8 and D1.5

meters. The Series 0 meters feature BS21

Series 0

DN40 screw connections which help to

facilitate low cost installation.

The models from 2” to 4” ( MRA100B to

MRA400D) share many components to

reduce cost and maximise flexibility. With

extruded aluminium bodies, an index with two

field-replaceable LF switches, and turndown

ratios of up to 200:1, these meters reduce any

unregistered gas and offer good network

performance and low maintenance costs.

Series 3 meters are the largest of the Delta

range. Tthe MRA650E and MRA1000E, being

metric equivalents of the D23 and D35 meter

offer a rugged approach to industrial metering.

The CORUS-PTZ Volume converter

range is EN12405 - compliant and will

operate with all LF-equipped meters.

The combination of reliable pulse

collection technology, PT1000

temperature sensing, precision pressure

sensors, and a 5 year battery life make

the Corus an accurate, reliable, cost-

effective solution for volume conversion

in both PT and PTZ applications.

The converter can provide pulse outputs

for use in external dataloggers, RS232

communications to modems, and 4-20

mA flow rate calculated from the LF

pulse rate.

No software is required to commission

the converter. All synchronisation and

pulse weight settings can be carried out

from the front panel, removing the need

for software and laptops for

commissioning.

*These meters are also available with “short” bodies: the DN150 (”E”) with 335 mm length,DN200 and 250 (”F” & “G”) with 400 mm length

“Fluxi 2000 TZ” Turbine MetersThe Fluxi range of turbine meters may be used

in specific installations for metering up to

6500m³/h of gas. These are used for

applications where flow is constant or varying

within a range down to1/20 of the maximum

flow rate.

Turbine meters are inferential meters. During

ioperation the flow of gas turns a turbine wheel

and the speed of rotation is proportional to the

linear speed of the gas. The motion of the

wheel is transmitted to the index via a

magnetic coupling.

A Fluxi 2000TZ turbine meter consists of 5

main components:

Main Body containing the flow and turbine

components

Flow straightener to accelerate and

stabilise the gas flow

Measuring unit including Turbine Wheel

Magnetic coupling to transfer the motion

of the turbine wheel

Index to register the volume of Gas.
