Introduction to electromagnetic water meter
MFB-K series electromagnetic water meter
Electromagnetic water meter features:
-
Easy installation, overall protection class IP68
-
Battery life: up to 6 years of service life
-
Range ratio: R=160, R=250,R400 ,R630
-
Low requiremenat for installation enviroment,can be installed with zero pipeline
suitable for DN50~DN300 (50mm ~300 mm carliber size)
Ultra low speed initial flow rate
-
Measurement accuracy, long-term measurement performance, maintenance-free
-
Can measure flow in both positive and negative directions
-
The battery water sensor can be equipped with a pressure sensor to detect the pipeline pressure at the installation point, which can be transmitted to the system.
-
The internal power supply is powered by a 3.6V high-energy lithium battery. It requires no external power supply and external settings. It is easy to use and has a wide range of applications.
-
Electromagnetic flowmeter or electromagnetic water meter housing is made of stainless steel (carbon steel optional)
-
A variety of communication solutions are available: RS485 communication, wireless remote transmission (GPRS\NB-IoT): remotely collect and detect electromagnetic water meter measurement information and alarm information to maximize customer convenience
-
The converter has a series of word diagnosis functions, electrode scaling, sensor leakage, empty tube alarm, low battery alarm light function, the user can detect the status of the water meter in real time.
-
Data protection: electromagnetic flowmeter parameters and measurement data are registered in non-volatile memory (can be stored for more than 10 years). The instrument has mechanical seal and electronic seal, which can effectively prevent parameters from being modified by unauthorized persons.
-
It is not affected by the density, viscosity, temperature, pressure and electroconductibility of fluid
DC/AC, battery power supply.
