Large LCD Screen & Monitor Flow Rate Support reading with Liter or Gallon unit, LPM/GPM switchable. DFC15 will display the flow rate(the REAL-TIME volume of liquid which passes per minute), the flow total volume and sensed temperature clearly. Quantitative control Controller will turn off the solenoid value automatically when flow reach to the setting value you desire. Work with all hall effect flow sensor It can work various different flow sensor through adjust the K value TECHNICAL SPECIFICATIONS Controller Power Requirement: 12VDC Power Adapter: Input: 100-240VAC, Output: 12VDC, max 2A Adapter lead length: 1m Measuring Accuracy: ±1% Output for Solenoid valve: 12VDC, max 2A Temperature Sensor: 0-100℃/32-212℉, NTC3950, Accuracy: ±1℃/±1℉ thread: M8 Max Total Volume : 999999 G/L Quantitative Range: 0-9999 G/L Flow Rate Range: 0-9999.99/LPM(GPM) Cable Length : 1m Dimensions: 88mmx126mmx30mm Weight: 200g Operation Environment: Temperature: 0-50℃/32-122℉ Relative Humidity: <85% For G1" Flow Sensor: Flow range:1-60L/min Allow compression:Water pressure 1.75 Mpa below Sensor:Hall effect Cable length:15cm Frequency: F=4.8 * Q (L / Min) For G1" Solenoid Valve: G1",thread male outer diameter: 32.5mm Working pressure:0.02-0.8Mpa Working Voltage:DC12V
