Electromagnetic Velocity Sensor for Open Channel Flowmeter
The EMV-500 is a water/wastewater electromagnetic velocity open channel flowmeter sensor which is available in two sizes:
SIZE A is suited for pipes or channels from 150 mm to 500 mm diameter.
SIZE B is suited for pipes or channels from 500 mm to 2.000 mm diameter.
The sensor is encapsulated in an IP68 submersible ultra high molecular polyethylene body to be mounted with a special sensor mounting band in the pipe.
When combined with the appropriate level sensor, the EMV-500 constitutes an efficient electromagnetic area/velocity flowmeter measuring both velocity and level in the same cross-section (or slice of pipe). This is a requirement necessary for accurate flow rate measurement using the continuity equation: Q = v x A
In addition, electromagnetic sensors are totally unaffected by the concentration of debris or dilution of wastewater by rain.
This sensor is also available in ATEX version.
