Difference between vented and non-vented water level measurement
A hydrostatic level probe typically uses pressure sensor to measure the water level. The main component of a pressure sensor is the sensing diaphragm which converts the difference in pressure between either side of the diaphragm into a measured signal. The front of the diaphragm measures the water level pressure (hydrostatic pressure) plus the barometric […]

Using Hydrostatic Pressure Transducers for Measuring Fluid Level
There are a number of methods and technologies for measuring the level of a fluid with hydrostatic pressure transducers.
Are all IP68 Water Resistant Protection Ratings the same
It is often assumed that devices with an IP68 rating are suitable for immersing underwater for an indefinite period at any depth. Not all devices that are IP68 are intended to be continuously submerged, some only require a temporary rating to protect from occasional submersion. For example a pressure transmitter installed below ground level will […]
Determining the Signal Cable Length of a Suspended Liquid Level Transducer
Deciding the correct length of cable for a suspended IP68 transducer is an important part of specifying, if the cable is too short it is difficult and expensive to join two cables together and make the seal liquid tight. There are two separate parts of the installation that need to be considered to determine the […]
Why are Submersible applications so demanding of Pressure Transducers?
Placing a sensing device in a liquid is one of the most hostile environments to ensure a long reliable service life. The extra considerations for design engineers include: Keeping pressurised liquid out. Preventing condensation damage to the internal electronics. Corrosion protection for all the materials used in the transducer construction. Adequate protection from lightning surges […]
Considerations for monitoring Landfill Water Level
In recent years regulations for environmental control, health and safety issues have become much more stringent for existing and new landfill sites. The regulations encompass many considerations and some involve the measurement and control of water level in many positions around a waste disposal site. One application is ensuring contaminated water is contained within a […]
How does changes in Local Gravity affect Hydrostatic Pressure
The value of hydrostatic pressure for a fixed height column of fluid is directly proportional to the gravitational strength at a particular geographical location. Generally if the height above sea level is increased the hydrostatic pressure will decrease. Also since the world is wider at the equator than the poles the gravitational pull will increase […]
Improve the electrical termination of vented submersible pressure sensors
Submersible cable is more expensive because it has to be reinforced to support the sensor plus its own weight in deep holes without stretching which would lead to a change in sensor position and ultimately sensor calibration. A submersible cable also has a vent tube running through it to allow gauge reference pressure sensors access […]
Measuring liquid level in a sealed tank with a hydrostatic pressure sensor
In order to measure the level of a liquid using a pressure sensor you must be able to subtract the pressure of the gas at the top of the tank.
