Open Channel Ultrasonic Flowmeter UFH-100
UFH-100 flowmeter measures free surface flows of such fluids as...
Typical Applications
・Supply water ・Agrigultural water
・River water ・Waste water
・process water ・industrial effuents
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.) |
||
| Alarm relay output | Water level measurement failure, flow velocity measurement failure | ||
| Display | 16 digit x 16 digit LCD display (with backlight) Flow value: max. 6 digits (incl. comma, decimal point) Water level: max. 6 digits (incl. m unit, comma and decimal point) Flow velocity: max. 6 digits (including m/s unit, comma and decimal point) Operation status indication |
||
| Power source | AC90V - 132V (50/60 ±2Hz) Standard AC180V - 250V (50/60 ±2Hz) (Option) |
||
| Power consumption | AC100V approx. 30VA AC240V approx. 40VA |
||
| Ambient temperature | -10C degree ~ 50C degree | ||
| Ambient humidity | Less than 90% RH (non-condensation) | ||
| Main unit configuration | Wall mount type IP5X (IEC60529 / dust proof) | ||
| Weight | Approx. 10 kg (approx. 11 kg with ultrasonic water level gauge) | ||
