TECHNICAL SPECIFICATIONS
EMV-1000™
EMV-1000™ SHEA
EMV-1000™ SHE B
Electromagnetic Velocity
Open Channel Flowmeter Sensor
The EMV-1000™ is an ATEX certified 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-1000™ 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.
Velocity Measurement
Method Electromagnetic (Faraday's Law)
Range 0 to +6 m/s
Accuracy ± 1% of measured value or ±0,03 m/s
(whatever value is bigger)
Min. conductivity of the medium needed
Velocity Measurement Method
10|jS/cm
The principle of magnetic-inductive flow measurements utilizes
the Faraday's law, where a conductor moving in a magnetic
field induces a voltage of amplitude proportional to the
velocity of the conductor. The conductor is the media being
measured.
