The Proteus EcoMeter P is a gauge specially designed for small tanks with fast and frequent level changes. The system consists of a mains-operated ultrasonic level sensor with integrated radio module (150m /492ft range to the radio display) and a separate, digital radio display, which is also mains-powered.
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).
Minimum height: 0,5m (19"); Maximum height: 3m (9.8ft)
Maximum measuring range: 3m (9.8ft)
Maximum volume: 19 999 litres (5300gal)
Sensor must be mounted at a distance of min. 20cm (8")of tank walls
Ultrasonic signal must not be disturbed by obstacles in the tank (cross bars, hoses, etc.)
Display of measured values, time, room temperature, critical battery status
Display (LCD) can be set and configured with 5 control buttons. The red WARN LED flashes when the level falls below 5% of the min.storage . A warning tone beeps hourly when the level is low.
Maximum range of the radio module 150m (492ft)(can be reduced by doors, walls, shafts, cover plates, etc.)
