Product Details

EcoMeter P (Power) ultrasonic level gauge for fast measurements with external power supply

In contrast to the EcoMeter, the Proteus EcoMeter P supplies the sensor with 3VDC voltage.  The sensor sends a new level signal to the EcoMonitor every 15 seconds. This means that rapid level changes during filling or emptying can be reliably detected.

A major advantage of ultrasonic level measurement is that no moving or mechanical parts have to be installed in the tank. This allows easy and fast self-assembly and reduces maintenance costs drastically, as the sensor cannot jam or "sink".

The EcoMeter P gauge measures the liquid level every 15 seconds and immediately transmits the value to the display, so that you always know the liquid level in your tank!

The ultrasonic method enables you to monitor the level in your tank by radio transmission anywhere within a radius of 150m (492ft) nd receive further information (see below).

Advantages of Proteus EcoMeter P

  • No wiring or special knowledge necessary
  • Wireless data transmission to the wireless display
  • Measuring range up to 3 meters /9.84ft (range of the ultrasonic signal)
  • Measures almost all tanks, regardless of manufacturer or construction material
  • Gauge splash-proof and suitable for outdoor use
  • Can be assembled and configured within a few minutes
  • Universally applicable: suitable for steel tanks, plastic tanks, cellar tanks, concrete tanks and cisterns or all external tanks.
