Your location the accuracy required and the ease of installation all contribute to determining the best water level sensor for your measurement site.
Water pressure measurement devices.
Pressure measurement devices such as inclined manometer bourdon gauge diaphragm gauge bellows pressure transducers and electronic pressure sensors are used to measure extreme pressures with high accuracy.
For pressure measurement in hydraulics analysis in civil engineering the knowledge of construction and working of these devices is a must.
Micro manometer u tube with enlarged ends.
Water pressure sensors can measure pressure in several different ways.
The diaphragm pressure gauge 6.
Bellows pressure gauge diaphragm pressure gauge.
This is similar to the way gas pressure sensors measure gas pressure as compared with a vacuum.
The barometer 2 piezometer or pressure tube 3.
Gauge pressure measures water pressure against the atmospheric pressure around the sensor.
Water level stage or flow can be measured with many types of sensors.
And the devices are.
You can also be called the types of the pressure transducer.
If the water.
Absolute water pressure is measured against zero.
The bourdon gauge 5.
Bourdon tube pressure gauge.
Vacuum pressure measurement device.
This can be an accurate means of measuring height but quality varies and some may be affected by fog.
Pressure transducers bubblers shaft encoders or ultrasonic sensors.
They measure the height of water by bouncing sound waves off the surface of the water and timing how long they take to return.
Ultrasonic measuring devices are typically installed directly upstream of a weir or box.
Here is the list of pressure measuring device pressure transducer.
