Description
Product Description
Battery Operated Flow Meter adopts lithium battery, which is capable of working 3~6 years consecutively. If a high-capacity battery is applied, the converter will have longer working time. The measurement of flow rate of the electromagnetic flow meter is based on Faraday’s law of electromagnetic induction. The battery powered electromagnetic flowmeter can be remotely communicated with the base station type radio communication network system. Date collection and management can also be realized through GPRS wireless network system. In addition, IP68 protection helps the flowmeter itself to be placed underground or underwater.
Advantages
The Battery Operated Flow Meter uses a specially designed sensor excitation system and a high-performance lithium battery power supply system. It uses all digital signal processing with the advantages of stable measurement, high measurement accuracy and strong anti-interference ability. It can optimize water supply and ensure accurate water trade measurement and settlement.
The equation is as below;
E=KBVD
K: Coefficient of the flow meter B: Pulsed magnetic flux density
V: Average velocity of the media D: Inner diameter of the measuring pipe
