Battery-powered electromagnetic flow meter

Description:
Xi'an Yunyi Instrument Co., Ltd Battery-powered electromagnetic flow meter, built 3.6V / DC battery, can work for longer than three years. At the same time using a specially designed sensor excitation system with full digital signal processing, anti-interference ability characteristics. Battery-powered electromagnetic flowmeter converter using LCD backlight LED display, even in bright light or at night can be clearly read.

Like other electromagnetic flow meter in our company,theAutomatic bi-directional flow measurement can be achieved, on-site instantaneous measurement, forward, reverse cumulative total display, GSM data wireless remote, self-diagnostic troubleshooting tips, and other functions. And there is an intelligent and smart sub-body size can be selected according to the site.

It is the most stable domestic battery-powered electromagnetic flowmeter , as well as the highest accuracy, the most power and convenient .
