Description

LS300 Liquid Level Sensor

The LS300 is an advanced 3-hole mounting fluid level sensor. It provides continuous, high-accuracy measurement of a tank’s contents.

Mounting and Mechanical Features

The sensor head footprint is extremely small and it features an AN-8 threaded mounting arrangement.

Reventec manufactures every LS300 liquid level sensor to the length required by the customer. This eliminates the need for users to modify the sensor and it simplifies installation.

LS300 liquid level sensors can be mounted in any orientation, including vertical inverted mounting. The sensor seals to the tank via a supplied radial O-ring seal.

We can supply sizes up to 450mm (see the LS345 for shorter length requirements) and the probe features a carbon-fibre outer layer, because this adds strength. It ensures reliability in high vibration and extreme operating conditions.

Accuracy, Outputs & Electrical Connectivity

The LS300 3-hole mounting fluid level sensor is available in two accuracy specifications:

  • +/-1% accuracy
  • +/-0.5% accuracy.

It is also available with a range of industry-standard outputs. A ‘low level’ alarm that activates when liquid drops below a calibrated level is available as an option.

Output options include:

  1. Analogue 0-5V (typically calibrated 0.25V empty, 4.75V full)
  2. Analogue 0-5V and Switch to Ground
  3. CAN and Analogue 0-5V
  4. CAN Only

Liquid level sensors come with a 500mm flying lead and the number of cores is dependent on the output mode(s). However, customers may specify a longer flying lead or for a connector to be supplied and fitted at additional cost. So if you require an integrated connector please ask us about our custom sensors. All sensors have an operating temperature range of -40°C to +125°C. An extended temperature range option is also available for operating temperatures up to 150°C.

Liquid Compatibility and Sensor Calibration

LS300 is compatible with all common liquid types, including fuel, oil and diesel. Sensors are available for compatibility with polar liquids, including water and coolant. In addition, LS300 can accurately measure bio-fuels such as Ethanol, Methanol and blends.

We calibrate every sensor in the customer-specified liquid type, so it is ready for immediate use. However, sensors can also be field-calibrated, for instance, if the liquid type is changed.
Reventec provides free calibration software, which is available on request. In addition, it lets customers compensate for non-linear tank shapes or where a non-linear output curve is desirable.
