Water Level / Pressure Sensor

A pressure-based sensor designed for measuring water level and hydrostatic pressure in water-monitoring applications.
The Water Level / Pressure Sensor is designed to sense hydrostatic pressure variations instantaneously and provide accurate water-level measurements. The sensor is designed to be free from atmospheric pressure variations, making it suitable for reliable water-level measurement. It can be used for wave measurements in flumes, tanks, and open sea, as well as accurate water-level measurements in notches or rectangular notches for total discharge measurement and discharge-rate studies.

Overview

The Water Level / Pressure Sensor is designed to sense hydrostatic pressure
variations instantaneously and provide accurate water-level measurements.
The sensor is designed to be free from atmospheric pressure variations,
supporting reliable water-level monitoring in experimental and measurement
applications.

The sensor is suitable for wave measurements in flumes, tanks and open-sea
applications. It can also be used for accurate water-level measurements
associated with discharge measurement systems.

Key Features

  • Designed for water-level and pressure measurement
  • Senses hydrostatic pressure variations instantaneously
  • Provides accurate water-level measurements
  • Designed to be free from atmospheric pressure variations
  • Suitable for flumes, tanks and open-sea applications
  • Suitable for discharge measurement applications
  • Compact sensor arrangement
  • 15-metre cable length

Measurement Principle

The sensor detects variations in hydrostatic pressure and uses these
pressure variations to determine the corresponding water level.
The sensor is designed to operate independently of atmospheric pressure
variations.

Applications

  • Wave measurements in flumes
  • Wave measurements in tanks
  • Wave measurements in open sea
  • Accurate water-level measurement
  • Measurement in notches
  • Measurement in rectangular notches
  • Total discharge measurement
  • Discharge-rate measurement studies

Wave Measurement

The Water Level / Pressure Sensor can be used for wave measurements in
flumes, tanks and open-sea environments. The sensor provides water-level
information based on the hydrostatic pressure variation detected during
the experiment.

Water Level Measurement

The sensor is designed to provide accurate water-level measurements.
Its design minimizes the influence of atmospheric pressure variations,
allowing water-level changes to be monitored reliably.

Discharge Measurement

The sensor can be used for accurate water-level measurements in notches
or rectangular notches. These measurements can be used for total discharge
measurement based on the relationship between over-flow level and the
discharge rate.

Installation and Use

The sensor can be positioned in the water body or measurement arrangement
where water-level changes need to be monitored. It can be used in
experimental flumes, tanks and other water-level measurement setups.

Measurement Range

The sensor provides a measurement range of 0 to 2 metres. The brochure
specifies an accuracy of 0.1% of full scale selectable, with an accuracy
of +/- 2 mm.

Cable Configuration

  • Standard Cable Length: 15 metres
Monitor up to 32 sensor channels simultaneously, with real-time recording, graphical monitoring and wave-data analysis from a single system.
