Diversity of Portalevel® Datalogger from the Range of Coltraco Limited

Coltraco being is a well known name in the world of measuring and monitoring instruments using ultrasonic technology. Coltraco make their products affordable and reliable without quality.

The Portalevel® Datalogger is an ultrasonic liquid level measuring instrument that is capable of storing the readings of up to 1000 cylinders. The collected data can then be uploaded to the computers which can provide fire service engineers with in accurate and easy to create service reports. Moreover, Portalevel® Datalogger being a non-invasive ultrasonic liquid level indicator is portable.

The conventional Portalevel® range is used for identifying the content of critical fire suppression cylinders but it is then left up to the operator to accurately record this elsewhere and complete the reporting processes to certify a system. It was the disconnect between the physical servicing and data recording that the Portalevel™ Datalogger was designed to overcome.

The liquid gas level indicator, services cylinders such as fire suppressant including old Halons, CO2, NOVEC 1230, FM 200 and others. The installed main unit is capable to manage date and time settings for logs unit. It further permits the cylinder position and number to be mentioned for accurate measurement.

How does the Portalevel® Datalogger operate?

  • The Portalevel™ Datalogger sends an ultrasonic signal directly into the cylinder using a sensor.
  • The sensor ‘listens’ to the ultrasound signal which is reflected back by the cylinder and its contents.
  •  It then automatically analyses this information and provides a readout to the user which represents how strong the received signal is.
  • The way the ultrasonic waves travel through different materials changes the signal which the Portalevel unit receives.
  • The changes in the received signal can then be used to identify the location of the liquid level in a cylinder to an accuracy of ± 1.5 mm.
  • There is a large change in readings from the gas phase to the liquid phase. By finding the exact point at which this change occurs the liquid level can be located.
  • The results can be downloaded onto a computer after testing by linking the unit to the computer with the provided USB cable and PC client software.
  • Using this technique, specific historical records can be built up on each system and the user can obtain verifiable proof of the system’s continuous inspection over time.
