Large-diameter Ultrasonic Water Meter

Features ●No mechanical moving parts, are not affected by the influence of impurities in water, long service life ●With ultra-low initiating flow, large measurement range which compared with the traditional mechanical meter. ●There will be alarms when the batter under voltage, empty pipeor non-full pipe and mal-function on transducer etc., ●Advanced design of low power consumption and high energy battery, ensure the battery life in 6 + 1 year. ●With infrared electric interface, using the infrared meter reading tools can realize the meter reading. ●With the M – BUS communication interface, easy to network to realize the real-time remote monitoring management.

Description

Overview
Ultrasonic water meter is a new type of full electronic water meter which is
by the detection of time difference generated from ultrasonic beam travels
in the water upstream and downstream, then calculate the water flow by
the analysis of water flow velocity.
