Product Description

Product Description
Taijia Open channel flow rate meter,ultrasonic flow meter for arduino ultrasonic flowmeterIntroduction of Open channel ultrasonic flow meterULFM series provides accurate non-contact ultrasonic open channel flow measurement Features of Open channel ultrasonic flow meter1.Open channel flow rate can be measure per 1mm according to the liqild level. The liquid level change 1mm.open channel flow rate changed with it. Measurement accurancy higher , flow measurement more accurante . 2.Suitable for variety of flume:Parshall flume,Right-angled triangle weir,Rectangular weir.3.Variety of flow rate unit is optional4.Fully closed structure, Strong anti-corrosion5.Strong anti-interference ability 6.Low blind zone,High sensitivity,High stability7.Provide at most 6 relay switch signal8.MODBUS-RTU digital signal is avaliable.9.The distance from transmitter to ultrasonic probe can up to 1000m10.AC and DC power supply is optional. 11.Romote control set up parameter is avaliable,Easy to operate. Transmitter of Open channel ultrasonic flow meterLiquid level resolution1mm.Liquid level error1mm or 0.2% of full measurement range (The maximum value, calm water)Display method2-line 14 LCD (with backlight)Instantaneous flow rate range0.0000~99999L/S or m³/hMaximum cumulative flow9999999.9 m³Analog signal outputone path DC4-20mA current corresponding to flow rate.Load resistance0~500ΩCommunicationsSerial communication,standard MODBUS-RTU protocol.Relay Outputupper limit ,lower limit alarm and control.( instantaneous flow rate and water level ) high level ,low level and breakdown alarm ect .Mode of relaynormally open or closed.(Can be setup)Quantity of relayat most six.Specification of relay5A 250VAC/30VDCPower supplyDC: DC24V(±5%) 0.2AAC: AC220V(±5%) 0.1ADetection Period1S ( can be adjust)Ambient Temperature-40C to +70CCasing materialsABSProtection grade of casingIP67Cable gland coverPG9/PG11/PG13.5Parameter setting method3 pcs inductive buttonsInstall methodWall mountedCasing Size186X183X126mm ApplicationUltrasonic Open Channel Flow meter is non-Contact instrument,Adopt Sound wave reflection principle to measuring liquid level in the water weir trough, Get the flow rate go thought the weir trough by conversion . The instrumeny mainly consist of ultrasonic probe and transmitter ,The materials in all plastic seal structure.can be widely application in Industry, environmental protection and ect industries.Measurement open channel flow rate accurately.
