Endress+Hauser developed the innovative Promag W 800 flowmeter with battery-powered operation. It provides maintenance-free operation for up to 15 years, as well as worldwide secure data transfer via cellular radio. The Promag W 800 electromagnetic flowmeter ensures not only reliable monitoring of water supply networks but also efficient and time-saving maintenance. Leaks can be located reliably, and non-billable water losses (non-revenue water) can be avoided. Promag W 800 is suitable for measuring lake, river, spring or groundwater flows for drinking and process water, as well as for applications in distribution networks subject to fiscal metering. Promag W 800 has a backlit display, making it quick and easy to read measured values. Endress+Hauser’s SmartBlue app can be used to interact with the flowmeter for operations and to provide more comprehensive data retrieval on site.
