UR-1000W complies with the technical standards for water meters qualification per the Metering Act. Ultrasonic water meters for proper metering of water use have a wide effective measuring range with a low dead zone. There is no actuator and pressure loss, so it has excellent durability during the validity period with built-in storage and communication functions for measured values.
UR-1000W ultrasonic water meter measures the water flow rate using an improved ultrasonic transit time difference method, which uses the principle that the speed of fluid changes the propagation speed of ultrasonic pulses. Arrival times of ultrasonic pulse are different as it propagates forwardly and reversely through medium (water) and the time difference proportional to flow velocity.
