Ultrasonic Water Meter

GUF142 Ultrasonic Water Meter | GAIMC

Product Overview

The GUF142 ultrasonic water meter adopts advanced transit-time measurement technology, featuring low power consumption, wide measuring range ratio, and stable reliable performance. With IP68 protection class for all components, it can operate continuously even submerged in 2 meters of water.

Equipped with a 58×22mm LCD display and smart touch keys, it supports bi-directional flow measurement (forward/backward instantaneous and accumulative flow) and multiple unit selection (m³, GAL, L, m³/h, GPM, etc.). Built-in lithium battery (3.6V, 19Ah) provides 6 years of service life, with optional DC8-36V external power supply.

Widely used in urban water supply, water resources management, irrigation, landscape management, industrial production and automation. Compatible with water, sewage, seawater (other liquids customizable) and pipe diameters from DN15 to DN300, with working pressure up to 1.6MPa (2.5MPa optional).
