Europe Standard Dn1200 Electromagnetic Flow Sensor Flowmeter
Converter
HKLD intelligent electromagnetic flowmeter is a kind of fully
intelligent electromagnetic flowmeter developed by our company with
advanced technology at home and abroad. Its Chinese electromagnetic
converter core uses high-speed central processing unit. The
calculation speed is very fast, the accuracy is high, and the
measurement performance is reliable.
Electromagnetic Flow Meters are based on FARADAY'S LAW INDUCTION.
These meters are also called as Magflow or Electromagnetic Flow
Meters. A magnetic field is applied to the metering tube, which
results in a potential difference proportional to the flow velocity
perpendicular to the flux lines. The physical principle at work is
electromagnetic induction and mathematically defined as E=k*B*D*V.
Features
(1) The obstruction to the flow is almost nil and therefore this
type of meters can be used for measuring heavy suspensions,
including mud, sewage and wood pulp.
(2) There is no pressure head loss in this type of flow meter other
than that of the length of straight pipe which the meter occupies.
(3) They are not very much affected by upstream flow disturbances.
(4) They are practically unaffected by variation in density,
viscosity, pressure and temperature.
(5) Electric power requirements can be low (15 or 20 W),
particularly with pulsed DC types.
(6) These meters can be used as bidirectional meters.
