Solenoid Valve with Water Flow Sensor - Normally Closed - Nylon - G1/2"

A standard solenoid valve with water flow sensor. With this, for example, the water flow in a hose or pipe can be measured and regulated.

The output of the sensor gives 9.4 pulses per second with a duty cycle of approximately 50% for every liter of liquid that passes through it per minute: Q [L/min] = f_pulse[Hz ]/9.4.

Modify the following piece of code around line 17:

float calibrationFactor = 4.5;

To:

float calibrationFactor = 9.4;

*Note: This is a factory specification under specific circumstances. Should the sensor be used in a situation where accuracy is required, it is recommended to calibrate the sensor in that specific setup.

**Note: We cannot provide any warranty when this product is used with any liquid other than clean spring/tap water (non-potable).

Note: The liquid can only flow in one direction, this is indicated by an arrow.

Note: The solenoid valve must be installed such that the coil is on top.
