Ultrasonic Open Channel Flow Transmitter Board
Description :
H760RO is a highly advanced and reliable ultrasonic open channel flow transmitter board designed for flowmeter to meet the diverse needs of flow measurement in various industrial and environmental applications.
Open channel flowmeter is widely used in water plant, sewage treatment plant, chemical reagent plant, dye plant, pulp plant and other factories level measurement engineering. It is one of the main liquid level measurement methods in modern intelligent automation industry.
The composition of sewage is complex and corrosive, and the liquid surface is easy to form floating objects. Therefore, the required level sensor is sensitive and reliable. Ultrasonic wave has the characteristics of strong signal penetration and sensitive response, which is the recommended choice for sewage level measurement.
