DIGITENDIGITEN Water Flow Control Meter LCD Display Controller+G1/2" Water Hall Sensor Flow Meter Flowmeter Counter 1-30L/min+G1/2" Solenoid Valve Normally Closed N/C+DC 12V Power Adapter
Main highlights- Work with All Hall Effect Flow Sensor: It can work with various different flow sensors through adjust the K value. High quality, come with temperature sensor, it can measure liquid temperature.
- Wide Applications: Swimming pool, water dispenser, coffee machine, drip irrigation system, beer brewing, etc. For example, if you want 5 liters of water, you can set up 5 liters of water on the DFC15 controller. When the water in the container reaches 5 liters, the controller will control the solenoid valve to close it, the water flow automatically stops, and you just get 5 liters of water. Please select a suitable flow meter. An oil flow meter is required for liquids other than water.
- Quantitative Control & Alarm Function: The controller will turn off the solenoid valve automatically when flow reach to the setting value you desire, it's easy to install and control. It can automatically stop water filling into your concrete mixer. When the total amount reaches the setting value, the controller will alarm.
- Package Includes & Warranty: Thread type: BSP, but it can work with NPT thread. The controller will come with G1/2" flow sensor, G1/2" solenoid valve(N/C), temperature sensor(it can measure liquid temperature) and 12VDC power adapter.
- 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.
