A Water flow sensor is a device which is used to measure the flow rate and water consumption for residential and commercial water filters. A Water flow sensor is a device which is used to measure the flow rate and water consumption for residential and commercial water filters. The main purposes are: water heater thermostat, water purifier, boiler, water dispenser, coffee machine,equipment, wall-hung boilers burning appliances such as water flow sensing the product interfaces diameter 7mm.

• Operating voltage: 5V -12vDC

• The flame sensor flame most sensitive reaction to ordinary light, is generally used as flame alarm purposes.

• the sensor and the flame to keep a certain distance to avoid high temperature damage to the sensor, lighter test flame distance of 760 to 1100nm. the greater the flame, the test distance farther

• Frequency F = 65 * Q (Q L / min), a 1.2mm inner diameter of the flow rate range 0.3-1.5L/min

• F = 40 * Q (Q L / min), 2.0mm inner diameter flow range 0.5-3L/min

• F = 26 * Q (Q is L / min), inner diameter of 3.0mm, flow range 0.5-5L/min

• The Q which said flow l / min, F is the frequency, suitable coffee machine water machine, flow range 0.3- 2.5L/min
