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 flowmeasurements.
It is applicable for liquids with free surfaces such as agricultural water, river water, waste water and industrial effluents.

Measurement Method

Specifications

Measurable liquid	Applications: agricultural water, river water, process water, industrial effluents, etc. Water temperature: 0~40℃ /Turbidity: ≤ 10000 mg/L (degree)
Measurement water channel	Water channel width: 0.3~20m (circular water channels φ0.3~5m) Needed channel straight run: standard - upstream ≥ 10B, downstream ≥ 5B (B: water channel width, pipe diameter in case of circular water channel)
Measurement principle	Flow: flow velocity x channel cross sectional area (water level) computation method Flow velocity: ultrasonic pulse transit time difference method Water level s from existing or any 2 wire level gauge (DC 4~20mA can be utilized
Measurement range	Flow: 0~full water level flow	Flow velocity: 0~10m/s	Water level: 0~10m
Output signals	Flow: 4~20 mA DC (allowable load resistance within 750Ω) with arrester element Flow Pulse: Capacity AC 3~250V / DC 3~125V Flow velocity: 4~20 mA DC (option: allowable load resistance within 750Ω) Water level 4~20 mA DC (option: allowable load resistance within 750Ω)
Accuracy	Flow     Forward flow: less than ±3% of full scale             Reverse flow: not specified as it depends on channel structure (+/- 10mm or better accuracy for level gauge required.)
