Measuring principle | Ultrasonic flow |
Product headline | Insertion meter with Heartbeat Technology and web server for the water and wastewater industry. Bidirectional flow measurement of water and wastewater. |
Sensor features | Low capital investment – cost-effectiveness increases with pipe diameter (up to DN 4000/156"). Long-term stable signal – maintenance-free permanent mounting from outside with coupling pads. Process transparency – diagnostic capability. Supports two parallel measurement paths. For large diameters: DN 200 to 4000 (8 to 160"). Medium temperatur: –40 to +80 °C (–40 to +176 °F). |
Transmitter features | Safe operation – no need to open the device due to display with touch control, background lighting. Full remote access – web server. Integrated diagnostics, verification and monitoring – Heartbeat Technology. Transmitter housing made of durable polycarbonate or aluminium. Remote version for wall mounting. Integrated data logger: measured values monitoring. |
