Endress+Hauser Promag W 800 wireless magnetic flowmeter

Endress+Hauser has developed the Proline Promag W 800 magnetic flowmeter for applications in remote areas where there is no possibility of supplying instruments with energy or transmitting data via cable. With battery operation, it is designed to allow maintenance-free, long-term operation for up to 15 years as well as worldwide secure data transfer via cellular radio.

The product has a backlit display that makes reading the measured values easy, and the SmartBlue app is used for operation and comprehensive data retrieval on site. The device is also available with various drinking water approvals such as KTW/W270, WRAS BS6920, ACS or NSF 61. The instrument offers a maximum measured error of ±0.5%.

The transmitter includes measuring electronics, batteries, a data logger and a cellular radio module to send and receive data via LTE Cat M1, LTE Cat NB1 or EGPRS. The cellular module can be used to call up measured values and status messages online, such as flow, pressure, totaliser, device and process status, alarm messages and level of battery charge. End-to-end encrypted data transmission offers security in data transmission. In addition, the extended data logger safely stores up to 50,000 measured values or entries.

Users can order the unit with a specially certified corrosion protection (EN ISO 12944) and IP68 (Type 6P) degree of protection, which completely prevents water ingress. The instrument also supports Endress+Hauser’s Heartbeat Technology to remotely monitor functionality and calibration.
