Introduction :
Insertion Type Electromagnetic Flow Meter is an Ideal solution for water flow measurements in large diameter pipes. Most economical as compared to its counterpart in full bore measurement or ultrasonic measurement. Insertion Type Electromagnetic Flow Meter is an Ideal solution for water flow measurements in large diameter pipes.
The Manas make Insertion Type Electromagnetic Flow Meter, called SROAT - 1000i is an ideal solution for water flow measurement in large diameter pipes. Fairly good accuracy of measurement (typically ± 1% of flow rate) can be achieved with little care in installation of probe and transmitter. The electrical conductivity of liquid under measurement can be as low as 20 µS/cm. Being insertion type, there is virtually no pressure loss. Most economical as compared to its counterpart in full bore measurement or ultrasonic measurement.
The technique called as “ Pulsed DC ” is used which offers very high zero stability and accuracy of measurement. The standard current output of 4-20 mA DC is provided which is linearly proportional to volumetric flow rate.
