GPRS Water Flow Meter For IoT Project 2G / 3G /4G Wireless Flowmeter For Agricultural Irrigation
Introduction
GPRS Water Flow Meter is a kind of induction instrument designed by Faraday’s law of
electromagnetic induction to measure flow of conductive media in
the tube. It adopts the technology of insertion of single chip to
realize digital excitation and employs CAN local fieldbus.
Electromagnetic flow meter can realize local indication and output
electrical current signal of 4-20mA which can be used to record,
adjust and control. 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.
Features
1. Simple structures, firm, no movable parts and long operation life.(Guarantee in 1 years)
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. LCD back light display with high clearness. (Option: LED back light display)
