Liquid Level Sensors

Forzmula’s expertise in capacitance and hydrostatic technologies has enabled us to develop electronic liquid level sensors without any moving parts to suit a wide variety of applications. These sensors are accurate, reliable and durable and can be configured with many different connections, thread and output options.

Fozmula Liquid Level Sensors TLL140

T/LL140

Capacitance Fuel Level Sensor

Electronic Liquid Level | Fuel Level |

A solid state fuel or oil level sensor T/LL140 series which provides a continuous output of tank contents in either resistance or voltage formats.

The sensor can be re-calibrated each time the tank is filled and can operate even with the inclusion of fuel additives.

Available for tank depths between 200 mm and 1100 mm it can also be cut to length by the user.

Fozmula Liquid Level Sensors TLL130

T/LL130

Capacitance Liquid Level Sensor

Electronic Liquid Level | Fuel Level | Oil Level | Coolant Level

A liquid level sensor which provides a continuous output of tank contents in either resistance or voltage formats.

Available for tank depths between 200 mm and 2000 mm it can be used in any liquids compatible with the wetted parts.

Fozmula Liquid Level Sensors TLL171

T/LL171 & T/LL174

Capacitance Liquid Level Sensor

Electronic Liquid Level | Fuel Level | Oil Level |

Occupying a tiny footprint, the vertically mounted sensors T/LL171 and T/LL174 are available in lengths between 90 and 500 mm long.

Offering good levels of accuracy at elevated temperatures, the T/LL17x series has an integral Packard Metripak 150 style connector. The T/LL171 provides a current output whereas the T/LL174 provides a voltage output.

Fozmula Liquid Level Sensors TLL350

LL350

Capacitance Liquid Level Sensor

Electronic Liquid Level | Fuel Level |

T/LL350 series provides a continuous level measurement of tank contents and offers a choice of voltage, resistance or 4-20 mA outputs. The dual probe design allows the sensor to continuously self calibrate and detect and will recalibrate the output to compensate for differing dielectric constants.

Therefore, if a tank is filled with conventional diesel and then bio-diesel, the sensor automatically calibrates to give a corrected output without the need for the user’s intervention.

TLL155 Cut to length fuel level sensor

TLL155

Fuel Level Sensor

Electronic Liquid Level | Fuel Level |

Designed for use in diesel fuel tanks and is available with a variable resistive, voltage or current output suitable for driving industry standard fuel gauges or connecting into PLCs.

It is supplied in standard probe lengths of 500mm or 1000mm and can be cut to length and magnetically calibrated by the end user.

Fozmula Liquid Level Sensors TLL300

T/LL360

Capacitance Level Sensor, Extended Temp Range |

Coolant Level

Capable of operating at temperatures as low as -40°C the T/LL360 series auto compensates when a liquid with a different dielectric constant is used.  For example, if it is used in a tank of conventional diesel, the user can refill with bio-diesel and the sensor will correct the output level automatically.

Options include a high/low level alarm point, fitment of any suitable connector and compensation for non-linear shaped tanks.

Liquid Level Sensors FR370

FR37x

Fuel Level Sensor with Integrated Feed & Return |

Electronic Liquid Level | Fuel Level |

Rochester FR37x range of Fuel Level Sensors are equipped with fuel feed and return pipes, removing the need for additional fuel extraction and filling connections and simplifying the fuel tank assembly and installation.

Fozmula Liquid Level Sensors TLL200SQ

T/LL200

Hydrostatic Liquid Level Sensor

Electronic Liquid Level | Fuel Level |

T/LL200 series is designed for use in tanks requiring continuous level measurement of their contents and provides a voltage or 4-20 mA output suitable for connecting into plc or process related applications.

Fozmula Liquid Level Sensors TLL130 Long

T/LL136

Race Fuels Level Sensor

Electronic Liquid Level | Fuel Level |

A liquid level sensor specifically for race fuels which provides a continuous output of tank contents in either resistance, voltage or PWM formats.

Available for tank depths between 200 mm and 600 mm it can be used with most aggressive fuel additives.

Fozmula Liquid Level Sensors TLL150

T/LL150

Capacitance Level Sensor, Cut-to-lenght

Electronic Liquid Level | Fuel Level |

This development of the popular T/LL130 series sensor can be cut-to-length and calibrated by the customer’s technicians. Available in standard lengths and outputs.

Oil level Sensors

T/LL400

Oil Level Sensor, Extended Temp Range

Electronic Liquid Level | Fuel Level | Oil Level | Coolant Level

T/LL400 Oil Level Sensor is an advanced capacitance sensor that continuously monitors oil level providing a configurable voltage output in the range 0-10 VDC.

Designed to provide accurate and repeatable level data for oil in relatively shallow, extended temperature range applications such as engine oil sumps or tanks.
