BMS4 Overview


BMS4 overview


BMS4

Advantages

• System integrated in one compact cabinet

• Modular concept • Standard configuration

• Tailor made solutions for any application

• Ideal for retrofit Installations • Can easily be adapted to existing/onboard solutions

• Works with any pressure, level and temperature

of liquid

• Automatic diagnostic during operation


BMS4

Advantages

• Automatic calibration of sensor during operation

• Automatic and continuous cleaning during

operation

• Less depending of air quality

• Reliable system for continuous operation


BMS4

Technical specifications

• Total number of control points for level

up to 100 points

• Draft control up to 6 points

• Power supply 220 V

• Power consumption up to 1.5W /channel

• Sensors power supply 24 V DC

• Protection level • of operator station IP20

• of local technological station IP54


BMS4 – LTS4 Local technological station

LTS performs the following functions:

• level measurement, by means of measuring

backpressure, which occurs in air mains of ballast

tanks

• Transfer of information of measured values into

the controller of the cargo system


BMS4

Operating principle

of the system

Data processing unit performs cyclical scanning of

the sensors:

• Contents of the measurement cycle: • Air injection into measuring tubes

• Time delay for pressure equalization

• Measurement of pressure, equal to pressure in ballast tanks

• Periodic calibration of sensors is performed


• Easy installation

• Designed for installation on ship

• Cabling, mounting etc.
