The Promag W 800, developed by Endress+Hauser, provides accurate measurement with maintenance-free operations and worldwide data transfer via cellular radio for up to 15 years.

For future-oriented communications, the Proline 800 transmitter includes measuring electronics, batteries, data logger and a cellular radio module to send and receive data worldwide via LTE Cat M1, LTE Cat NB1 or EGPRS.

It can be used to call up measured values and status messages online, such as flow, pressure, totalizer, device and process status, alarm messages, level of battery charge and more.

For onsite data collection, Promag W 800 has a backlit display that makes reading the measured values “quick and easy.” Endress+Hauser’s SmartBlue app is used for operational and more comprehensive data retrieval.


“The integrated Heartbeat Technology makes it possible to monitor Promag flowmeters continuously, verify their functional capability at the press of a button and thus provide evidence of consistently high measuring accuracy within the specification.”
