This flow sensor can be used with any Select Doser.
This sensor has a 1" thread and can operate with water flows up to 3,600 l/hr.
Small particles are unlikely to block a turbine flow sensor. However, if water is coming from an open water source, you will need filtration for sure.
If the sensor does get blocked, try removing the sensor and flushing with fresh water. Do not use a high pressure water source for cleaning.
