Large-caliber ultrasonic water meter

Communication mode

Product feature

■ Customizable mono, dual or four-channel products.

■ Low initial flow, high accuracy level.

■ Wide range ratio, the default is R125:1, 160:1、250:1、 400:1、 500:1 are optional.

■ IP68 protection grade and IP65 protection grade are optional.

■ Micro-power design, battery-powered, real-time measurement, theoretical work on one battery for more than 10 years (power consumption is less than 0.4mW ).

■ Maximum measurement accuracy can be guaranteed under various flow regimes.

■ No mechanical rotating parts reduce power consumption of water pump.

■ High stability, can work at any flow point for a long time, and the measurement is not subject to magnetic interference.

■ Forward and reverse measurement, plastic and metal meter head optional.
