Hydrostatic level gauges: What is it?

Hydrostatic level gauges are reliable and easy to the difficult conditions. Their advantage is low cost with good accuracy and wide range.

the

applications

Instruments of this class are optimized for liquid products with different density. However, some types are used for gas. Possible areas of work:

the
  • Chemical industry (measurement of liquids level in tanks, etc.);
  • the Oil and gas industry (assessment of the level of gas in tanks, and different fuel);
  • Utilities (measurements of boreholes and wells; monitoring of sewage);
  • Agriculture and environmental monitoring (determination of water level in a natural body of water, control of water in reservoirs settlements and businesses);
  • Food industry (dairy products, alcoholic beverages, commercial accounting);
  • Pharmaceutical industry (alcohols, ethers);
  • the Metallurgical, mining (dredging, underground water, wells);
  • Production of marine equipment (monitoring and control of vessel);
  • Galvanoservice.

the Primary measured parameter of the instrument is the pressure, so such gauges are also used for continuous registration of limit values of medium pressure. By the way, to buy hydrostatic gauges from the leading manufacturers .

the

Purpose

These devices are suitable for a wide range of tasks:

  1. Continuous monitoring of pressure and level of water or other liquids of different density, the contamination and aggressiveness (acid, highly viscous and pasty products);
  2. measure the level of gases in the tanks;
  3. Commercial metering of liquid products;
  4. Tracking level in large tanks and open containers (such as swimming pool or bodies of water / storage to a depth of hundreds of meters);
  5. temperature Measurement in boreholes (some models)
  6. data logging environmental measurements for further use in the automated system;
  7. Alarm system on certain events (e.g. reaching a certain temperature and level);
  8. Monitoring of water level in artesian wells;
  9. the Study of groundwater, wastewater, natural water;
  10. Inspection of narrow pipes and other difficult to reach places;
  11. Protection of submersible pumps from “dry” (return) stroke;
  12. management of technological processes in automated systems (such as pumping stations or Sewerage system);
  13. the Control and monitoring of the emptying of the storages;
  14. monitoring of the settlement and position of the ship / vehicle.
the

Types of appliances

There are two basic types of hydrostatic gauges. By way of attaching to the process, they are divided into:

  1. flush;
  2. tagliblocation.

Sometimes isolated flange method which fundamentally differs from the one just mentioned. Conventionally, the transmitters can be divided according to the properties of the working environment: environments that are non-aggressive to the materials of the device, as well as aggressive and polovicna environments. Certain structural features and requirements impose chemical and hygienic requirements to the device.

Mortise devices are compact devices that are installed at a certain point of the tank. Devices of this type are best suited for level measurement of liquids, gases, or commercial accounting in stationary storage tanks of different sizes.

Gauges taglibraries type containing a special probe that is lowered into the tank or the hole to the required depth. Such devices should be selected in the applications related to survey of wells, any open tanks or natural basins.
