Introduction
The Endress+Hauser Proline Promag W 800 is a battery-powered electromagnetic flowmeter purpose-built for off-grid water and wastewater applications. Featuring a 15-year battery life, IP68 protection, and LTE encrypted communication, it delivers reliable, maintenance-free measurement in remote, underground, or underwater installations with no external power required.
Key advantages
1. 15-year battery life for off-grid use: Eliminates the need for external power, making it ideal for remote water and wastewater installations with no electricity supply.
2. IP68-rated for harsh environments: Fully protected for direct underground or permanent underwater use, with EN ISO 12944 corrosion protection for long-term durability.
3. Global encrypted LTE communication: Supports LTE Cat M1/NB1/NB2 and GPRS, enabling secure, worldwide data transmission without on-site infrastructure.
4. Custody transfer accuracy: Certified to MI-001/OIML R49 with ±0.5% measurement error, suitable for billing and custody transfer applications.
5. SmartBlue app & Bluetooth control: Offers convenient commissioning and remote operation via Bluetooth and the SmartBlue app, even in hard-to-reach locations.
