Type 804 EM Insertion Flowmeter

Electromagnetic Insertion Flowmeter Valeport’s Type 804 is a fully waterproof, electromagnetic insertion flowmeter that offers industry-standard performance coupled with robust build quality and reliability, all backed up by Valeport’s exceptional customer service and support.

Electromagnetic Insertion Flowmeter Valeport’s Type 804 is a fully waterproof, electromagnetic insertion flowmeter that offers industry-standard performance coupled with robust build quality and reliability, all backed up by Valeport’s exceptional customer service and support.

Our Type 804 insertion flowmeters will measure bi-directional flow rates as low as 0.02ms-1 and up to 5 ms-1 with accuracies of better than 0.002ms-1. Add a real-time temperature measurement we can help you manage your water distribution networks.

A highly cost-effective solution due to reliability, ease of installation and recovery, with no interruption to supply, for pipe diameters from 100mm to 2000mm.

  • A standalone Type 804 has up to 4 years battery life, as standard
  • The flexibility to interface to all data loggers, telemetry systems or SCADA systems through fully documented and open data protocols
    – Available protocols: pulse | RS232 | RS485 | Modbus RTU
    – Other outputs include: 4 – 20 mAmp through the DDM

Valeport Water can provide telemetry and logging options with the EnviroLog 4G.
