ETG S.r.l products

What is and what is used for: The pressure exercised by a liquid is proportionate to its height, and in this way it is possible to determine its level by measuring the pressure. The resistance and compatibility with the fluids of the various components, type of material the instrument case, seals and electrical cable are made of are essential in this application.

The PPS-L sensor was introduced in ETG’s proposals to solve problems relating to their PPS mechanical cousins Like in every system subjected to mechanical friction and wear and tear, the wire level measurement systems are subjected to deterioration. More specifically, this deterioration is tied to the steel wire and to the recovery mechanism, which therefore require periodic maintenance. ETG proposes the most modern, practical and highest performance laser distance sensors. As regards the measurement principle, the laser sensor will be pointed in the direction of a stainless steel plate welded to the flood gate.

The ETG Clamp On is a device that measures the water flow rate in a pipeline based on the principle of the difference of transit time of an ultrasonic pulse. An acoustic (ultrasonic) signal is transmitted in both directions by one sensor to the other. The propagation velocity of the acoustic waves in the flow direction is greater than that in the opposite direction and, as a result, a difference in transit time proportionate to the flow velocity is calculated.

What is and what is used for Designed to meet all real-time monitoring requirements, it was built to interface with all existing weather instruments. Equipped with built-in GSM/GPRS card and memory card, it downloads data locally or sends them to an IP address for downloading via web.

The air humidity sensor consists of a membrane of hygroscopic material that forms the dielectric of a capacitor so that the water molecules in the air are absorbed by the dielectric, thus causing a change in the capacitor’s capacity, due to the humidity, to which a change in the oscillation frequency of an electrical circuit connected to a sensor corresponds, which in turn transforms it into a change in direct voltage. The probe produces a signal/noise ratio.

WQ0X is ready for the assembly of up to 12 sensors, used to measure quality parameters in surface and underground waters.
