Flow Battery Powered Electromagnetic Volume Totalizing MeterETM3070

Battery Powered Electromagnetic Volume Totalizing Meter ETM3070


*Specifications are subject to change without prior notice.

Capable of maximum 15 years' continuous measurement with an inhouse battery, ETM3070 series electromagnetic volume totalizing meter has attained an eco-friendly and reliable high-performance measurement.
The measuring tube is Lined with Rilsan® widely used for coatings for the inside of city water pipes, the tube with reduced size has significantly increased the accuracy in the domain of low flow measurement.
This flowmeter is applicable for the vast variety of services in water related industries.


  • · The in-house lithium battery allows maximum 15 years' continuous measurement without changing the battery.
  • · The measuring tube made of aluminum die-casting lined with Rilsan® is very resistant to creeping deformation caused by vacuum pressure.
  • · Reducing measuring tube size The measuring tube with reduced size offers high accuracy in low flow measurement with a short upstream straight runs as short as 3D. (D is pipe diameter.)
  • · No earth rings are required with earth electrode equipped as standard.
  • · A touch panel system by an infrared sensor allows you to alter the settings without removing the cover of the flowmeter.
  • · High accuracy of ± 0.5% of reading.
  • · Pulse and status outputs are standardized.
  • · Empty flow detection.
