The TU2000 is a non-contact ultrasonic level transmitter from Novus, measuring distance, level or volume in liquids, solids and grains up to 20 metres. Because it uses sound rather than light or contact, readings aren't affected by smoke, colour or reflectivity, and nothing touches the product being measured. Built-in temperature compensation keeps readings stable as conditions change.
Setup is done from your phone or PC with the free SigNow app over Bluetooth, with a guided commissioning wizard, echo graph diagnostics and firmware updates. Up to 20 linearisation points let it report true volume in horizontal, conical or irregular tanks.

Frequently Asked Questions
Can it measure solids and grain as well as liquids?
Yes — the TU2000 measures liquids, solids and grains, in static or moving media, which makes it suitable for silos as well as tanks.
Do I need a configuration cable?
No — it's set up wirelessly over Bluetooth using the free SigNow app on a phone or PC.
Can it report volume rather than level?
Yes — enter up to 20 linearisation points and it outputs volume, even for horizontal or irregular tanks.
Can it trigger an alarm without a PLC?
Yes — the configurable PNP/NPN output (up to 200 mA) can switch a relay or alarm directly, alongside the 4-20 mA signal.
Industry Applications
- Silos & grain storage — non-contact level of solids and grains up to 20 m.
- Water treatment — tank, sump and channel level monitoring.
- Industrial tanks — cylindrical, vertical, horizontal or irregular vessels.
- Rivers & reservoirs — remote level monitoring.
