Water reservoirs are the largest quantity of drinking water for municipalities and cities. The supply of such water, and in some cases of rivers and streams, must be carefully managed as a source of drinking water.
Ground water obtained from deep wells is also an important water supply for many communities with flat geography. It should be particularly well managed, since it can take decades to clean and refill the aquifers from which water is taken.
The supply of surface water and groundwater, requires a wide range of detection and control devices for optimal management of these valuable resources. Since the water found in the surface can be easily contaminated, it is necessary to control the pH level, toxicity, and turbidity, before processing for consumption.
The submersible hydrostatic pressure sensors provide control and level monitoring for wells and reservoirs. Ultrasonic sensors offer a new and simple alternative to control water surfaces and wells basins. The transducers can be used to control river basins as well as positioning of the gates of the dams.
The telemetry products and systems can be used as remote control of environmental variables, using various techniques of wired and wireless communications. The loggers can record environmental data for future download or manual collection.
They remotely transmit the position where a gate is found. Aluminum body. Output 4-20 mA (two wires), potentiometer or pulses. IP 65 protection.
- PT8420 – PT9420 – For linear displacement dampers. When the ring is pulled, the cable rolls out, spinning the reel, which moves a potentiometer or encoder, giving a signal proportional to the length of the cable removed.
- IT920 – For angular displacement dampers. Inclinometer. In its interior there is a pendulum attached to a potentiometer or encoder shaft. To swing up to 270 º. Magnetic damping of vibrations.
- RT9420 – For any outlet gate in the axis of rotation. It counts the number of of rotation degrees of the damper shaft.
This level meter emits a sonic wave that bounces off the water and returns the echo to the probe. This evaluates the time and calculates the distance. Since the speed of sound in air varies with temperature, the probe has a temperature sensor that compensates for changes. Provides a 4-20 mA output plus programmable relay and local display. The ranges are 3, 6, 10, 15, 25 and 40 meters.
