Every equipment type in Cargo Level & Temperature Gauging links to full manufacturer and model data, specifications and service notes.

Radar Level Gauge
Radar gauges read cargo level from the top of the tank by timing a microwave pulse reflected off the liquid surface, so they need no moving parts inside the tank and keep working through vapour that would fool a float or capacitance probe.
2,157 models
Pressure/DP Transmitter
Pressure/DP Transmitter
A pressure or differential-pressure transmitter infers liquid level in a cargo tank from the hydrostatic head the liquid exerts, a robust but density-dependent alternative to radar or float gauges, and the DP version cancels out tank pressure changes that a single pressure transmitter alone cannot.
267 models
Temperature Sensor
Temperature Sensor
A cargo temperature sensor answers a different question than a level gauge: not how much cargo is present, but what state it is in, and on refrigerated or heated cargoes that number can decide whether the tank stays within its design envelope.
213 models
Ultrasonic Level Gauge
Ultrasonic Level Gauge
An ultrasonic gauge times a sound pulse's round trip to the liquid surface through the vapour space above it, which makes it simple and cheap but sensitive to vapour density, foam and turbulence in a way that radar and servo gauges are not.
109 models
Servo Level Gauge
Servo Level Gauge
A servo gauge tracks the cargo surface by lowering a small displacer on a wire until it senses the buoyancy change at the interface, then holds that position — a mechanical measurement, not a reflected signal, which is why it stays accurate on cargoes that radar struggles with.
99 models
Float Level Switch
Float Level Switch
A float level switch gives a single discrete signal — high, low or a fixed intermediate point — rather than a continuous reading, which is why it is fitted as an independent high-level alarm even on tanks that already carry a radar or servo gauge.
90 models
UTI Equipment
UTI Equipment
A UTI device is the portable probe lowered on a graduated tape through a vapour-lock valve to read ullage, cargo temperature and the oil-water interface by hand — the fallback and calibration check for the tank's fixed radar gauge, not a replacement for it.

Knowledge

What a Cargo Level & Temperature Gauging engineer checks first.

A radar level gauge sits on the tank top and sends a microwave signal down through the vapour space to the liquid surface, then measures either the time the reflection takes to return, known as pulse radar, or the frequency shift of a continuously swept signal, known as FMCW radar, to calculate distance and therefore level. Unlike a float gauge or a servo tape, nothing moves inside the tank, so there is no mechanism to jam, no tape to snap and no float to sink in a dense or viscous…

Would you like to know more?

One request. A person answers within 24 hours on working days.

Tell us the manufacturer, the model and what you need — a part, a service call, a second opinion. Our desk asks the right suppliers from a network of over 114,000 companies and comes back with a quote or a sourcing plan, not a search page.

Frequently asked

Three things people ask first.

Is Cargo Level & Temperature Gauging data free?

Yes. Every model page, every guide and every datasheet in this category is readable without an account. An account adds saved searches and requests, nothing is taken away.

My model is missing — what now?

Send us the nameplate. We identify it by hand, add it to the library, and if you need a part or a service, the request is already on our desk.

Can you source a Cargo Level & Temperature Gauging part?

Yes. Tell us the manufacturer, the model and what you need — our desk asks the right suppliers from a network of over 114,000 companies and comes back with a quote or a sourcing plan.
