Online help for BLE Gauge

General product information

Beim BLE Gauge is a compact, battery-powered, stationary sensor for recording the fill level of fresh or grey water. The measurement is carried out using a piezoresistive pressure sensor that has to be immersed in the medium to be measured. Thanks to the internal battery and to the data transmission via local radio connection, the device works independently. The ultra low power technology allows for a long battery life time (up to 5 years) with both short measurement intervals and high resolution.

Product specifications:

  • ATEX certified for zone 1
  • High resolution
  • Large measurment range
  • Short measurment interval
  • Compact dimensions
  • Up to 5 years battery life due to ultra low power technology
  • Data transmission via local radio connection
  • Very low commissioning and operating costs

Fields of application:

  • Stormwater management ponds
  • Sewage systems and industrial plants
  • Municipal water and wastewater systems

This online help is valid from:

  • Firmware version: 01v000

Frequently asked questions (FAQs)

The BLE Gauge does not have a special transport mode. I.e. it is always ready for operation and does not have to be activated.

The zero point (position of the diaphragm) is located at the level of the notch at the lower end of the metal housing of the pressure sensor. Measure the installation height from this reference plane. The red line in the illustration marks the zero point.

Please note that the position of the diaphragm results in a minimum fill level of 20 mm provided the pressure sensor is not installed below the zero level (e.g. in a pump sump).

Using a compatible data logger, the values for mounting height and trimming can be transmitted to the BLE Gauge . Both values are taken into account when calculating the fill level (see Determining the fill level).

With a Jellox for instance, mounting height and trimming can be set via the configuration section "Remote measurement channels".

Fill level = (installation height + output value of the pressure sensor) + trimming

Calculation of the measurement value "Fill level"

Installation height 30 cm
Output value 15 cm
Trimming 5 cm
Fill level 50 cm

The BLE Gauge does not have a special transport mode and therefore does not need to be deactivated.
