GFM-2 Ultrasonic Open Channel Flow meter

GFM-2 Ultrasonic Open Channel Flow meter suitable for water conservancy, hydroelectricity,environmental protection and other open channel of industrial and agricultural measurement.The instrument equip the explosion-proof sensor design specifically for the oil and chemical sector,especially suitable for oily waste water flow measurement. It using ultrasonic through the air to measure the height of water level in open channel by a non-contract way,then automaticly calculates the value of corresponding flow by microprocessor.Liquid crystal display the instantaneous and accumulated flow when measuring flow rate and display the liquid level ,upper and lower alarm indication when measuring liquid level.EEPROM digital storage allows the data never lose when power outage. Technical specifications:Range of water level measurement0-0.3mMinimum water level resolution(mm)±1mmMeasurement accuracy±3‰ of system errorRange of flow measurementDepends on the type of weir/slot,999999m³/h maximumOperating temperature-20°C-60°CBlind spot0.3mOutput signalRS485,4-20mA,2-4Power supplyDC24V/150mA;AC220/100mAProtection gradeIP65
