Applications
Where the Tank Liquid Level Indicator 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
- OEM customers pairing sensors to their own console
- Service and spares distributors
- System integrators building a multi-point install
Quality
How it is tested
Every Tank Liquid Level Indicator 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.
OEM and ODM
Building it under your brand
The Tank Liquid Level Indicator is available as an OEM or ODM build: own-logo and own-package builds and console artwork and unit selection (°C/°F, mm/inch, m/s or mph). MOQ runs from 300 to 1,000 pcs depending on model and delivery is normally 35 to 45 days; our own R&D team handles new development rather than subcontracting it.
Where it sits in the range
Inside Weather Sensors and Transmitters the Tank Liquid Level Indicator reads 3 parameters; if you need more on the same console, the FT025T Weather Station Sensor-UV carries 7.
