Tekelek’s TEK898 NB-IoT pressure sensor offers a configurable, battery-powered device designed to safely measure liquid levels and pressure in tanks.

An ATEX approved device, with the TEK898 you can remotely monitor liquid levels and pressure within fixed, mobile or underground tanks. Example use cases for this NB-IoT Ultrasonic tank level sensor include:

  • Liquid pressure levels
  • Fuel – Gasoline, Kerosene, Diesel
  • Lubricants
  • Additives
  • Oil and waste oil
  • Water
  • Selected Chemicals *contact us to check compatible products

Suitable for use with fixed, portable or underground tanks, data recorded by the TEK898 will be transmitted from the sensor by the connected NB-IoT network which is fulfilled by inserting a compatible SIM card.

With the option to utilise programmable alerts, the TEK898 NB-IoT Presure sensor can be used to alert you to:

  • High/low pressure levels
  • Rates of level change

Utilising NB-IoT technology, this device can be easily connected by inserting an NB-IoT SIM card. Check coverage in your area.
