Tokyo Keiki UFH-100 Open Channel Ultrasonic Flowmeter

UFH-100 Open Channel Ultrasonic Flowmeter

UFH-100 flowmeter measures free surface flows of such fluids as :

Typical Applications :

・Supply water ・Agrigultural water
・River water ・Waste water
・process water ・industrial effluents

The TOKYO KEIKI UFH-100 ultrasonic flowmeter system for open channels employs the latest in ultrasonic and microwave technology. Utilizing our wealth of know-how and technical expertise, the UFH-100 system combines an ultrasonic flow rate meter with a microwave level gauge to provide accurate and stable flow measurements. It is applicable for liquids with free surfaces such as agricultural water, river water, wastewater, and industrial effluents.
