Ultrasonic wireless water level gauge for rainwater tanks and cisterns, underground water tanks

Proteus EcoMeter S is - like its brother, EcoMeter - an ultrasonic liquid level sensor, battery powered and equipped with a digital radio transmitter. This device has been developed especially for water tanks, rainwater and cisterns - but it can also be used for continuous measurement of the fuel tanks content (eg. diesel). The intelligent algorithm responds quickly to level changes in the tank (e.g. during refilling of water or fuel several times per day, or pumping the tank content out).

To ensure maximum battery life, the sensor sends measurement data to the receiving station every 30 minutes. Measurements are also provided in real time, but as soon as the detected change in the level of a tank is ≥ 1 1/5" (3 cm) / min.

Like EcoMeter, EcoMeter S is a modern and precise alternative to mechanical dipsticks and content meters of water tanks, barrels and cisterns with a maximum capacity of 5300Gallons (19.999 liters), offering a measurement range of up to 9 9/10" (3 m). The sensor communicates wirelessly with digital radio station within range up to 500ft (150 m).

Optional antenna extension (EcoMeter S PLUS)

An additional cable with a length of about 30ft (9 m) between the sensor and wireless module allows you to install the sensor in underground tanks and cisterns, manway opening or hard to access and radio dead areas(e.g. behind thick walls, heavy lids or shafts/manway openings at depths greater than 8" (20 cm) below ground level).

It also allows for the installation of the sensor in the radio dead areas, thereby extending the effective working range of the monitor. EcoMeter PLUS is thus able to provide a stable connection between the sensor and monitor at depths in excess of 8" (20cm) and in places covered with heavy metal or concrete covers blocking the radio signal.

Please note that the conversion of the Ecometer to the version with an antenna extension cannot be carried out by the customers. In case you wish a conversion, please return the device to us. Our specialists will be happy to do it for you.

Installation Notes 

• To ensure optimum working conditions, make sure that the Proteus EcoMeter sensor has been installed at a suitable distance from tank walls and obstacles inside tank of at least 6" (15 cm) in order to avoid distortion of the ultrasonic signal.
• The maximum measurable volume of the tank is 5300 Gallons (19,999 liters).
• The sensor must be mounted directly on the tank cap or the fuel filler cap and must not be mounted on flange longer than 8/10" (2cm). If possible, remove the nozzle and attach the sensor directly into the threaded opening.
• Please specify the distance between the sensor opening/membrane and bottom of the tank (= height).
• Maximum range is 10ft (3m), the ultrasonic sensor can take readings only within this area.
• Please be aware that heating oil tanks are governed by TÜV, so any modifications (eg. drilling) can be undertaken only by professional staff with relevant license. These objections do not apply to water tanks and cisterns. Please keep all possible implications in mind.
• The optional antenna extension cable (approximately 30ft (9 m) between sensor and transmitter) can be separated (at the user's own risk, the guarantee does not cover modified cable).
• For sensor installed deeper than 8" (20 cm) in the tank or below ground level, the antenna extension (EcoMeter PLUS) must be used.
• Please download the latest version of the manual before Installation Guide (available below).
