Applications

Where the FT0021 Water Tank Level Meter is used

Water tank and cistern level

Level is read from the console instead of by climbing to the tank hatch, which is the whole point of the ultrasonic head.

Problems it removes

  • Outdoor conditions guessed from a phone app that reports the nearest airport, not the site.
  • Someone climbing to a tank hatch to see how much is left.

Who buys it

  • Cold-chain and catering equipment suppliers
  • Wine, cigar and instrument storage brands
  • Baby, nursery and home-comfort retailers

Quality

How it is tested

Every FT0021 Water Tank Level Meter is aged before it leaves the factory and is checked on the same equipment the rest of the range uses: constant temperature and humidity chambers, radio link checks over the rated range, and vibration and smog aging equipment. A ten-person QC team inspects and tests in process, and the weather station line holds CE (GTS verification of compliance, RED 2014/53/EU) and FCC authorisation under FCC ID 2ALHJ-WS0300.

In the box

  • Install the battery in the battery compartment of the transmitter, do not insert the battery compartment, and insert the battery synchronously after the receiver is set up
  • The liquid level indicator has no data, press the tank key, and the data will be displayed
  • When reset, remove the battery Wait for a while and then turn on the power to eliminate the remaining power in the machine
  • Whether the red light of the transmitter flashes, the flashing is normal, and vice versa
