FAQ

Question?
What is the HART protocol used for with this PROWIRL 72W flowmeter?

The HART (Highway Addressable Remote Transducer) protocol allows for two-way digital communication over the same wires as the 4-20mA analog signal. This enables remote configuration, diagnostics, and monitoring of the device without interrupting the primary flow measurement signal, greatly simplifying maintenance and calibration.

The pressure rating of a wafer-style flowmeter depends on the flanges it is installed between and the type of gaskets used. Always refer to the manufacturer's documentation for the specific pressure and temperature limits based on the flange rating (e.g., ASME B16.5 Class 150, 300 or DIN PN16, PN40) to ensure safe operation.

Yes, the Prowirl vortex flowmeters are designed to measure the flow of gases, steam, and liquids. However, for saturated steam applications, it is crucial to ensure correct installation and possibly use an upstream condensate pot to prevent damage and ensure measurement accuracy. Always verify the process temperature is within the device's specified limits.
