Ultrasonic, wireless heating oil level sensor

EcoMeter is an innovative, ultrasonic level sensor and energy consumption monitor designed specifically for heating oil tanks in private use. EcoMeter is modern and an accurate alternative to mechanical dipsticks and other mechanical devices. EcoMeter can be used with tanks up to 5300 Gallons and 10ft height. EcoMeter has already been sold in more than 1 million times throughout Europe.

EcoMeter consists of a transmitter and a receiver unit. The transmitter, also called sensor, monitors the level of liquid in the tank as well as the cost, consumption and the CO2 emissions.

It is supplied with a CR2450 lithium battery, which under normal operating conditions provides a lifetime of 2-3 years.

The transmitter sends data wirelessly to a main electricity powered receiver, EcoMeter monitor equipped with a large LCD display.

Advantages of Proteus EcoMeter

• No risk of running out of fuel: Unlike comparable devices, EcoMeter allows you to not only to measure the liquid level in the tank, but also to calculate the remaining volume of the liquid in the tank and displays the estimated “Days To Empty”.
• Compatibility: EcoMeter device is the compatible with all types of commercial and custom tanks with 2", 1 ¼" and 1 ½" threaded openings.
• Accuracy: Measurements made using ultrasound technology are up to 10 times more accurate than comparable mechanical or electronic measuring devices.
• Quick and easy installation: The installation of the EcoMeter needs no moving or mechanical parts to be installed in the tank. This provides both quick and easy installation and significantly lowers the cost of operation and maintenance, because the procedures do not require specialized skills or knowledge.
• Cost control: the display of historical cost, consumption and energy enables a better control of energy usage and cost.
• Reduced energy consumption compared with previous generation electronic oil level monitors.
• Comfortable: Monitor your tank and consumption conveniently from the comfort of your "living
• Precision: The best alternative to mechanical gauge clocks, plungers and fuel dip sticks - and a lot more precise!
• Domestic and factory use: suited for domestic as well as factory heating fuel use monitoring

Optional antenna extension (EcoMeter PLUS)

An additional cable with a length of about 30ft 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" 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" and in places covered with heavy metal or concrete covers blocking the radio signal.

Easy 6-Step-Installation

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" in order to avoid distortion of the ultrasonic signal.

• The maximum measurable volume of the tank is 5300 Gallons.

• 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". 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, the ultrasonic sensor can take readings only within this area.

• Please be aware that some heating oil tanks have certifications, 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 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" in the tank or below ground level, the antenna extension (EcoMeter PLUS) must be used.
