Usa Standard Atex Water Sewage Electromagnetic Flow Meter For
Liquid Propane
HKLD type intelligent electromagnetic flowmeter is a fully
intelligent electromagnetic flowmeter developed by our company
using the most advanced technology at home and abroad. Its
electromagnetic converter core adopts high-speed central processing
unit. The calculation speed is very fast, the precision is high,
and the measurement performance is reliable. The sensor adopts
non-uniform magnetic field technology and special magnetic circuit
structure, the magnetic field is stable and reliable, and the
volume is greatly reduced, the weight is reduced, and the flowmeter
is characterized by small flow.
Application
Due to its unique advantages, it is widely used in the fields of
petroleum, chemical industry, steel, light industry, sewage
processing, environmental protection, water conservancy project and
pharmacy to measure the volume flow of the conducted liquid
mediums, such as acid, alkali, salt solution and so on.
Features
1. No moving and blocked flow parts in the pipeline, almost no
additional pressure loss in the measurement.
2. Measurements results are independent of physical parameters,
such as flow distribution, fluid pressure, temperature, density and
viscosity.
3. On-site modification of the measuring range available.
4. LCD display, easy to use and simple to operate.
5. Using SMD devices and SMT technology.

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.
