Termékleírás
The FA(R) DI ZG20 / ZG21 vane wheel inline sensor is a precise small measuring tube designed for stationary flow measurement of gases and liquids. The system is available with internal diameters of 9.7 mm, 18.2 mm, or 25 mm and includes a robust connection housing.
The models can be supplied either with an integrated UFA transmitter or for connection to a separate evaluation unit. The ZG20 version includes integrated inlet and outlet sections, while the ZG21 version is equipped with compression fittings.
Depending on the version, the probe material is made from stainless steel or aluminum, allowing operation at media temperatures up to 370 °C. The device is suitable for measuring operating volume flow in air, gases, gas mixtures, water, and liquids. In addition to clean media, the sensor can also be used temporarily in contaminated media.
An optional flow direction detection function is available. Signal processing can be performed using the integrated UFA transmitter, the flowtherm NT handheld device, the flowtherm Ex, or other compatible system devices.
