Introduction
The ATWU series gas ultrasonic flowmeter is based on the principle of ultrasonic time difference method. It is equipped with independent digital temperature transmitters and pressure transmitters, and integrates a wireless remote transmission module. It is a velocity-type gas metering instrument that integrates flow measurement, volume correction and remote data transmission. It features high measurement accuracy, good equipment reliability, low pressure loss and wide measurement range. It can meet the high-precision measurement requirements of the urban natural gas metering industry and can be widely applied in the gas flow measurement of trade handover fields in urban gas, chemical, power, metallurgy and other industries.

This type of product, with no movable parts and a self-diagnostic function, can help reduce the workload of engineering and maintenance for gas operators, lower the supply and sales gap, and enhance the level of lean management. The online monitoring system equipped at the same time can achieve comprehensive data collection and diagnostic analysis of the equipment. It can also set parameters of the equipment according to the authority, and the operation is simple.
