Water Level Sensor For Deep Well Pump

The PT-988 Level pressure transmitter is a measuring tool for water tanks and deep well pumps. pressure transmitter adopts an imported sensor core and a stainless steel isolated small structure. It has a wide range and a variety of output signals. This product has good stability in a wide temperature range and is widely used in water conservancy monitoring, underwater environment work, tap water pipeline systems, underground water pipeline pressure measurement, industrial process pressure measurement, etc. Can directly replace many similar products.

Water Level Sensor Main feature:

  • Compact design, laser welding sealing method;
  • Stable sensor core, high cost performance;
  • IP68 waterproof all-stainless steel housing;
  • Waterproof and anti-corrosion cable export;
  • High precision and wide measuring range;
  • A variety of pressure interfaces and signal outputs are available.

How to Choose a


level sensor?

In order to choose the technology that will best suit your process, it is important to know the nature of the product that will be measured. Is it a liquid, paste or loose solids? If it is a liquid, is there foam on the surface of the liquid?
Level measurement technologies can be divided into two groups: contact and non-contact. Non-contact technologies are more appropriate for use in extreme environments or with aggressive products. Non-contact level measurement also has the advantage that there is no risk of contaminating the product.
As with any sensor, the measuring range is very import and care must be taken to consider the position of the sensor in relation to the product. For example, if you install a sensor at the top of a silo and there is 1 meter in height between the sensor and the maximum height of the product in the silo, you must take this meter into account when evaluating the level range to be measured.
It is important to choose a level sensor that is resistant to the pressure and temperature of the process conditions and has an output signal that is compatible with the measuring system: analog or digital output; with or without display; relay output; etc
