Work with All Hall Effect Flow Sensor: It can work with various different flow sensors through adjust the K value. Come with temperature sensor, it can measure liquid temperature. Large LCD Screen: DFC15 will display the flow rate(the real-time volume of liquid which passes per minute), the flow total volume and sensed temperature clearly. Custom icons on the display indicate the controller working status at a glance. Water Meter Function: Support reading with Liter or Gallon unit, LPM/GPM switchable. DFC15 can be used to measure the volume of water. Wide Applications: Swimming pool, water dispenser, coffee machine, drip irrigation system, beer brewing, etc.
