Electro Magnetic Dn10 to Pn300 Magnetic Flow Transmitter For Liquid Caustic Soda

Electro Magnetic Dn10 to Pn300 Magnetic Flow Transmitter For Liquid Caustic Soda

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. The circuit design of the converter adopts international advanced technology, the input impedance is up to 10 ohms, the CMRR is better than 100db, and the rejection ability for external interference and 60Hz/50Hz interference is better than 90db. It can measure the flow rate of fluid medium with lower conductivity.
 
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.
(7) The meters are suitable for most acids, bases, water and aqueous solutions because the lining materials selected are not only good electrical insulators but also are corrosion resistant.
(8) The meters are widely used for slurry services not only because they are obstruction less but also because some of the liners such as polyurethane, neoprene and rubber have good abrasion or erosion resistance.
(9) They are capable of handling extremely low flows.

Precautions
1. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields, so as to avoid the magnetic field affecting the working magnetic field of the sensor and the flow signal.
2. should be installed in a dry and ventilated place, to avoid sun and rain, the ambient temperature should be -20 ~ +60 ° C, relative humidity is less than 85%.
3. There should be plenty of space around the flowmeter for easy installation and maintenance.

Installation requirements
The measurement principle of the electromagnetic flowmeter is that it does not depend on the flow characteristics. If there is a certain turbulence and vortex inside the pipeline, it will be generated in the non-measurement zone (such as elbow, tangential current limit or half-opening shut-off valve upstream). Measurement is irrelevant. If steady-state eddy currents in the measurement zone affect the stability of the measurement and the accuracy of the measurement, then some measures should be taken to stabilize the flow rate distribution:
A. Increase the length of the straight pipe before and after.
B. Using a flow stabilizer.
C. Reduce a section of the measuring point.
