Tokyo Keiki UFH-100 Open Channel Ultrasonic Flowmeter

 - Measurement:
+ Application : Free surface flows such as agricultural water, river water, waste water, processing water, industrial effluents, etc. 
+ Fluid temperature : 0 ～  40°C
+ Turbidity Less than SS10,000mg/L 
- Measurement Range:  
+ Flow rate : 0 ~ full water level flow 
+ Water level : 0 ～ 10m 
+ Flow velocity :  0 m ～10m/s
- Output signal: 
+ Flow: 4~20 mA DC ( R within 750 ohm)
+ Flow pulse: AC 3~250 V/ DC 3 ~ 125V
+ Flow velocity: 4 ~ 20 mA DC
+ Water level: 4 ~ 20 mA DC
- Measurement Accuracy : 
+ Flow rate (Flow velocity level calculation method )  : Forward flow: ±3% FS 
+ Water level : Depends on level gauge used.   
+ Flow velocity (Ultrasonic pulse transit time difference method ) : ±1%RD  (for flow velocity above 0.8m/s)   . ±8 mm/s (for flow velocity less than 0.8 m/s) 
- Display : 
Flow rate: dependant on max. flow value setting (max 6 digits, including comma, decimal point) 
Level: dependant on max. level setting
