FAQ

HAST-C22 (Hastelloy C-22) is a highly corrosion-resistant nickel-chromium-molybdenum alloy. Its presence means this Promag 50P is suitable for measuring extremely corrosive liquids, such as wet chlorine gas, hypochlorite, and various acids, where standard stainless steel electrodes would quickly fail.

Yes, the Promag 50 transmitter includes a HART communication protocol. This allows it to be configured, calibrated, and diagnosed using any HART-compatible host system, including Endress+Hauser's FieldCare software or a standard HART communicator handheld device.

The K-factor is a calibration constant specific to this individual sensor. It represents the number of pulses generated per unit of volume passing through the meter. This precise value is determined during factory calibration and is programmed into the transmitter to ensure the flowmeter's specified accuracy of 0.5%.
