Simple, Cost Effective Level Sensor
TL400-I is a proven solution for measurement of liquid levels, including fuels. The non-intrusive sensor can be mounted to tanks of varying shapes and sizes. It can perform accurate measurements up to 4 Metres distance with an accuracy of +/- 2mm. Installation is simple thanks to an industry standard M12 connector and free Bluetooth configuration tool. The sensor comes complete with a gasket/seal kit.
Ideal for detecting liquids, grains, fluids and bulk solids in static and moving applications. The 4-20mA output can be configured to provide a proportional signal based on distance, level or volume. With a harmless pulsed laser beam it performs fifty measurements per second while an advanced algorithm calculates the exact level and converts it to volume in litres or other desired units.
- Easy non-intrusive installation

- Up to 4M measuring range
- Configuration via Bluetooth with free App
- Digital filters based on Machine Learning
- Allows linearisation for any irregular tank geometry
- Converts level into volume (litres, m3, gallons)
- 150mm Female M12 connection (2 x cores power, 2 x cores signal)
- Pressure rated to 6 Bar
- Industrial quality with 3 Year Warranty

Novus TL400-I Level Sensor FAQs
Q. Can this sensor detect water?
A. Yes the sensor can reliably detect water.
Q. What is the viewing angle and how can this assist you?
A. The viewing angle can be adjusted via software between 15-27 degrees. A narrow angle of 15 degrees can help to avoid obstacles. A wide angle can be used to get a better average measurement of a wide surface area.
Q. How should the sensor be mounted?
A. It is important the sensor is mounted horizontally i.e. completely level. Try to avoid reflections from different light sources. Mount away from physical obstacles for example not too close to the tank wall or any other obstacles
Q. Can the sensitivity be adjusted to avoid rapid fluctuations?
A. The Filter parameter can be adjusted to dampen or debounce the measurement. A recommended initial filter value of 10 will help to give a stable signal.
Q. Does the sensor failsafe or provide any error signal?
A. You can set the sensor to provide a low or high level 4-20mA output in the event of error.
Q. Can the sensor cable be extended?
A. The cable can be extended with a female 4 pin M12 cable. This type of sensor cable is widely used in industry and available from us here
When using a standard M12 4 pin sensor cable to extend the cabling the final wire colours for termination are typically as follows. If in doubt please confirm with a multimeter:
Brown = +24V Supply In
Blue = 0V Supply In
White = mA Out +
Black = mA Out -
