Sea water Electromagnetic Flow Transmitter Meter Negative Pressure
Resistant Electromagnetic Flowmeter Flow Meter
Introduction
KEF series electromagnetic flow meters are intended for fluid
measurement in most industries including Electromagnetic flow
meters are widely used in industrial sectors such as chemical
industry, environmental protection, metallurgy, pharmaceutical,
paper making, water supply and removal etc.Besides measuring flow
of general conductive liquid electromagnetic flow meter can measure
flow of liquid-solid mixed fluid, high-viscosity fluid and salt,
strong acid and strong alkali.Electromagnetic flow meter can
realize local indication and output electrical current signal of
4-20mA which can be used to record, adjust and control.There are
two basic components of electromagnetic flow meter: 1) The
Detector, which includes the flow tube, isolating liner and
measuring electrodes, and 2) The Converter, which is the electronic
device responsilbe for signal processing, flow calculation, display
and output signals.The materials of construction of the wetted
parts( liner and electrodes) should be appropriate for the
specification on the intended type of of service. Revies of the
compatibilities consistent with the shipment of each meter.
Features
1. LCD back light display with high clearness. (Option: LED back
light display)
2. No intercepting fluid parts, no pressure loss and fluid
clogging.
3. No mechanical inertia, quick response and good stability,
application in automatic examination, adjustment & controlling.
4. Measuring accuracy not influenced by physical parameters such as
style, temperature, viscosity, density and pressure.
6. Supply many styles of flow meters such as inline type and
insertion type, etc.
Adopt EEPROM memory to measure operation data, safe and reliable
protection of memory.
7. Integral type flow meters and remote type flow meters.
8. Simple structures, firm, no movable parts and long operation
life.(Guarantee in 1 years)
