Flow meter

TU 4213-008-49652808-2004

Designation and options:

Volume flow rate measuring of pressure control system waste water with telemetric data display.

Modifications with interface RS-485 or current output 4-20mA are also possible. Modification of the flow meter with LCD indicator allows to control instant and cumulative flow rate on the front panel of the device.

Principle of action:

Measuring of the electromotive force induced by geomagnetic field in the conducting fluid proportional to the average speed of the flow. Volume flow rate that goes through the pipelinetransforms intomultiple electric pulses with data grade circuit (0.001 m3, 0.01m3, 0.1m3, 1 m3), this format can be modified on the Customer’s request.

Characteristics:

• Wide range of operating pressures (up to 21MPa)
• Operation with the increased gas ratio
• Operation with high flow inhomogeneity near pipe bends, adjustable chokes, back pressure valves and gate valves
• Absence of structure elements in the flow through. Pressure drop doesn’t exceed pressure drop in the pipelines of the same length

Modifications:

• General purpose
• With indication (I)
• Explosion-proof
