Electromagnetic flow measurement system, takes care of all your flow measurement and monitoring needs with maximum efficiency. The system comprises of a magnetic flow tube and an electronic flow converter. Specially designed flow coils, generate a magnetic field in the flow tube. As the conductive fluid moves in this field, voltage proportional to the the velocity of fluid is generated in the electrodes. This voltage is received by the flow convertor, and digital signal processing is done before the flow value is displayed in the illuminated alphanumeric lcd.


The totalizer value is protected in an eeprom in case of power failure. The flowmeter uses advanced digital technology with intelligent software systems combined with precision engineering ensuring accurate and reliable flow measurement.

Product Details:

Flow Range0.5m/sec to 5m/sec
Frequency50 Hz
Voltage220 ~ 240 V
Sensor ExcitationDC 12 V
Totalizer Range255 million 999999 litres

Principle of Operation:
The most commonly employed measurement principle is to measure the liquid's velocity and the pipe area flow rate = velocity x area. The haris paddle wheel flow sensor, works on this simple but accurate principle. Four blades spin past a sensor in the housing body. As the fluid flow causes the rotor to rotate, a signal is produced proportional to the flow rate. The design of the rotor ensures a linear repeatable output upto a flow velocity of 7 m/sec with an accuracy of ± 0. 06 m/s. The signal is fed to the fully digital, user programmable flow meter for a digital display of flow rate. & totalized flow. The pdlc 4080b can be used for batching applications. Haris flow meter allow field calibration of sensor for achieving maximum accuracy. Advanced digital damping filter with users settable time factor ensure steady readings in pulsating flow conditions. In the event of power failure the non volatile memory retain its configuration and fertilizer data.
