Added to Your Cart:
The PG25 variant of the weFlux² flow sensors simultaneously measures the flow velocity and temperature of water, deionized water, and PG25. It is factory-calibrated for the water-glycol mixture used in liquid cooling, primarily in primary circuits at risk of freezing, but also in secondary circuits.

** The sensors were factory-calibrated for the PG25 medium and specified for this application. Technically, the sensors are suitable for a temperature of medium down to -25°C. To achieve a temperature below 0°C, the concentration must be increased. This results in a deviating measurement result, which is why use below 0°C must be tested individually for the specific mixture being used.
