Neuron Liquid Level

The Neuron Liquid Level is a battery-powered wireless sensor designed for accurate monitoring of liquid levels across a wide range of applications.

The pressure sensor is housed in a rugged, compact stainless-steel enclosure and connected via a 5-meter cable to an external radio transmitter.

Experience how easy it is to get started and the huge benefits of our simple and practical IoT solutions.

An integrated long-life battery enables up to 10 years of maintenance-free operation, ensuring long-term reliability even in demanding environments.

All measurement data are easily accessible through a web interface, mobile app, or API, allowing for seamless integration and real-time monitoring.

General Description

The Neuron Liquid Level utilizes a submersible 0–1 bar gauge pressure transducer to measure liquid pressure. The pressure transducer is connected to the wireless radio transmitter via a 5-meter cable, which represents the maximum allowable distance between the two components.

To maintain accurate level measurements, a pressure relief valve located near the transmitter compensates for variations in atmospheric pressure.

Because this valve must remain above the liquid surface, the sensor can accurately measure liquid level changes up to approximately 4.5 meters.

Although the total liquid depth may exceed 4.5 meters, only variations within the top 4.5m are detected.

The conversion from pressure to level is handled in the app. Use the configuration helper tool for easy conversion. You can also apply an offset if you wish to include the level below the sensor’s position.

The sensing element supports media temperatures from –40°C to +125°C and is compatible with liquids suitable for 304 stainless steel.

 

Principle of Operation

The Neuron Liquid Level Sensor consists of two components: a pressure transducer and a radio transmitter.

The pressure transducer is completely sealed and can be submerged. The radio transmitter powers the pressure transducer and read the pressure signal thru the provided cable and sends the data wirelessly to the Neuron Gateway. The radio transmitter has a strong build-in magnet for secure fastening on magnetic materials.

Every 30 seconds the sensor measures the pressure and if the pressure has changed more than the critical trigger since the last transmission, the sensor reports immediately. Otherwise, it reports every 2 minutes.

 

Features

  • Long life battery – up to 10 years lifetime
  • Continuous measurement and instant alarm
  • Adjustment of parameters such as measurement frequency on request

Installation

Neuron sensors are ready for use out of the box and will start logging data after registering the sensor in the app. Even though Neuron sensors deliver great range and long battery life, following some simple guidelines for mounting of the sensor and gateway can greatly improve signal coverage and lifetime of the sensor.

To ensure optimal antenna performance and signal strength, the sensor should be placed elevated with some distance to fixed objects. Keep in mind that RF-signals are greatly affected by close metallic surfaces.

For sensors with an external antenna, the antenna should be clear off the metallic surface.

For sensors operating in environments with greatly varying temperatures, care should be taken to avoid putting the sensor in unnecessary stress. Very high or low temperatures will affect the battery life and the signal strength of the sensor. While some sensors must be close to the source of heat or cold, other sensors have external probes which allow the sensor to be placed at a distance..

Fastening
The small, compact blue Neuron sensors are fitted with fastening holes for use with cable ties. The sensors are also delivered with double-sided tape that may be used for fastening of the sensors.

All the black Neuron sensors, like the Neuron IR380 and Neuron Vibration, are fitted with a strong magnet at the back for easy fastening. If there is no magnetic surface, then double-sided tape is a good solution.
