Product Description


Is stationary time difference ultrasonic flowmeter flow body could be water, sea water, or oil, uniform liquid slurry, conduct electricity or not, corrosive or no corrosive liquid can be measured. 

Widely used in industrial field of various liquid flow metering online, which host is divided into standard wall hanging type, plate type, hanging type explosion-proof, the use of different field in order to meet user needs.


Product features

Low fixed ultrasonic flowmeter with large planning integrated circuits CPLD, table process, accuracy is higher.

Price, high reliability, high performance, good applicability, full display in Chinese.

Day, month and year flow accumulation function, can record run 64 days before the operation, the first 64 months, the first five years of accumulated flow operation.

On low, the power management function, can record, electricity and traffic on 64 times before, can be manually or automatically compensate to reduce flow losses.

Low effectively overcome the wall of the ultrasonic signal attenuation and rough surface of the pipe to scattering of ultrasonic signal from surface reduce the energy consumption of ultrasonic signal.

Low overcame a signal to a small amount of sediment, suspended particles and bubbles, the effect of improved flow measurement accuracy, especially suitable for pipe flow measurement.

When using a dedicated open hole tool that sensor in the zone without water supply installation, unique belt roller disassembly, installation method, does not affect the normal production, 

at any time to complete the on-line replacement and maintenance.
