Eliminate costly concrete protective vaulting. The Promag W 800 sensor body features a fully welded construction protected by certified EN ISO 12944 C5-M anti-corrosion coating. This allows direct soil burial or permanent operation under flooded chambers (IP68 / Type 6P) without seal degradation.
Conventional mechanical water meters create internal throttling and high pressure drops, increasing pumping energy costs over time. The Promag W 800 features an obstructionless full-bore liner design with no moving parts. With the optional 0 x DN calibration, it delivers ±0.5% certified accuracy directly downstream of elbows, valves, or pipe reducers with zero straight pipe run required.
Field technicians can configure parameters, extract data logs, and run diagnostics through pit glass windows using the secure SmartBlue Bluetooth app. Onsite manual meter reading is replaced by automated daily volume reports transmitted securely worldwide via integrated cellular modems (LTE Cat M1 / NB-IoT / GPRS).
Ensure strict metrological compliance without removing the meter or interrupting process flow. Integrated Heartbeat Technology provides continuous internal device verification and generates ISO 9001:2015 compliant verification reports attested by TÜV SÜD.
Answer: Promag W 800 is commonly used for water distribution, wastewater treatment, irrigation and industrial water measurement applications.
Answer: Customers can submit project requirements including size, lining material, electrodes and communication requirements for quotation support.
Answer: Technical datasheets, configuration information and project documentation support can be provided during the RFQ process.
Answer: Yes. With the optional 0 x DN full-bore option, the Promag W 800 maintains ±0.5% accuracy even when installed directly downstream of elbows, valves, or pipe reducers without straight pipe requirements.
Answer: The internal 3.6V lithium battery pack provides up to 15 years of continuous operation, depending on the configured measurement intervals and cellular telemetry transmission frequency.
