Hydrostatic Level Sensor

Hydrostatic Level Sensor (Best Price), also called Hydrostatic level transmitters,

for Hydrostatic level measurement.

Continuous level measurement in liquid applications with pressure sensors.

In hydrostatic level measurement,

the measuring cell of the pressure transmitter detects even the slightest changes in hydrostatic pressure,

which increases or decreases depending on the filling level.

The acting pressure is converted into an electrical signal by the integrated electronics,

and then outputted as an output signal.

Different types of measuring cells are used in level measurement based on the hydrostatic principle.

Hydrostatic level measurement: Measuring Principle

Contite cell:

The measuring cell is absolutely protected between the process isolating diaphragm,

and the rear isolating membrane.

Also it is absolutely insensitive to condensation and aggressive gases.

Ceramic cell:

The ceramic sensor is a dry sensor,

i.e. the process pressure acts directly on the robust ceramic process isolating diaphragm and deflects it.

A pressure-dependent change in capacitance

is measured at the electrodes of the ceramic substrate and the process isolating diaphragm.

Let’s see How does hydrostatic level measurement work?

What is hydrostatic gauge? Or,
What is a hydrostatic level sensor?

Hydrostatics is the science of fluids not in motion.

A hydrostatic level sensor is a form of a level probe,

that is used especially for level monitoring,

by measuring the hydrostatic pressure,

in a virtually static liquid at a pre-determined level of submersion.

A hydrostatic level sensor is a submersible pressure transmitter,

that has a pressure diaphragm,

where the inner side of the diaphragm is vented to atmospheric pressure,

through a vent tube in the cable,

and the outer side is in contact with the liquid,

and measuring the static pressure of the liquid column above the transmitter.

This static pressure is basically caused by the weight of the fluid on top of the transmitter,

and is used to calculate the level of the liquid.

How does a hydrostatic level sensor work? Or
How is hydrostatic pressure measured?

When considering a new level sensor for level measurement applications,

it is often hard to find information on how the different types of level sensors,

like the hydrostatic level sensors respectively hydrostatic pressure sensors, are working.

Recently, I explained level measurement by using the hydrostatic pressure measurement.

In closed geometries, such as enclosed tanks and vessels,

generally, flush pressure sensors or pressure transmitters are used,

which can be screwed into the vessel from the outside.

Pressure sensors are therefore particularly suitable,

in applications of free-standing tanks and vessels.

A submersible pressure transducer

or a flush pressure sensor

measures the height-dependent weight-force of the liquid column,

also known as hydrostatic pressure.

This pressure measurement is directly proportional to the liquid level respectively liquid column,

at the measuring point of the pressure sensor.

It is, therefore, necessary, for the measurement of level,

that the pressure sensor is placed as close as possible to the level of the vessel’s bottom.

The measured hydrostatic pressure then directly corresponds to the height of the liquid column,

from the ground-level measurement point to the surface-level of the medium.

So, the filling height is calculated from the distance of the medium surface,

to the measuring point by the pressure measurement.

The weight force of the liquid column,

thus the hydrostatic pressure, however,

is not only directly proportional to the filling height

but also varies with the specific gravity of the medium and the force of gravity.

Hydrostatic level sensor in use

The simplicity of using a hydrostatic level sensor,

makes it the instrument of choice wherever level needs to be measured,

no matter if in a vented tank, vessel, lake, river or reservoir.

In most cases, it is suspended by the cable to the desired level of measurement,

or just submerged and allowed to sink to the bottom of the resource.

It does not matter what the structure of the tank,

basin or natural geometry is or if it has any obstructions,

ledges or complex shape,

a hydrostatic level sensor will always measure the pressure of the liquid unaffected by such disturbances.

As the hydrostatic level sensor commonly is a gauge pressure sensor,

it automatically compensates for the atmospheric pressure changes,

so the pressure measured represents only the pressure of the liquid,

caused by the liquid’s specific gravity and the vertical distance to the surface.

Therefore, the hydrostatic level sensor accurately measures the level of the liquid,

by calculating the distance from the measuring point to the surface level via the measured pressure.

A hydrostatic level sensor may be calibrated

in metres water column to allow for standard gravity or local gravity.

For very high accuracy level monitoring often the temperature of the media,

may also be considered to take the temperature effects on the specific gravity into account.

The hydrostatic level sensor is a specialized sensor for level monitoring,

most commonly used in the water and wastewater industry.

Its simple use and reliable and accurate measurement technology

make it one of the most commonly used level sensors by far.
