PF3W is a digital flow sensor that constantly monitors water or coolant flow. PF3W refreshes the design and operating performance of the legacy PF2W model. This is the remote version of PF3W7, with a display. One or two analog outputs are available, depending on whether the optional temperature sensor is selected. Additional options include a mounting bracket, flow adjustment valve and

Model PF3W504 PF3W520 PF3W511 PF3W540 PF3W521 Note 1) Refer to Measurable Range for Ethylene Glycol Aqueous Solution on page 6. Measurement can be performed with a fluid that does not corrode wetted parts and has viscosity of 3 mPas [3 cP] or less. Be aware that water leakage may happen due to internal seal shrinkage or swelling depending on kinds of fluid.
