Point level measurement is the process of detecting the level of liquids in a container using a point level sensor. The data it provides is important because it informs you when a container is full or needs more liquid. This prevents overfills and keeps the process and/or facility running smoothly.

How a Point Level Sensor Works

A point level sensor is a device that detects the level of liquid in a container. There are two types of point level sensors: high level and low level. High-level sensors detect when liquid is present in the container. Low-level sensors, in turn, detect when there is no material present.

You can categorize liquid point level sensors between invasive and non-invasive.

• Invasive point level sensors are those that come into contact with the liquid. They work by using a method such as a float or a probe to measure the level of the liquid. These sensors suit non-hazardous liquids, like water or beverages.
• Non-invasive point liquid level sensors are those that do not come into contact with the liquid. They work by using a method such as sound waves, light waves, or radar to measure liquid levels. Non-invasive point liquid level detectors are for liquids that are corrosive or hazardous. These include acids, liquid metals, and poisons.

Applications of Point Level Measurement

Facilities use point level measurement for:

• Leak detection – to prevent damage to equipment or production downtimes
• Level measurement – to maintain accurate data and prevent run dry or overspills

Many industries use point level measurement, including:

• Food and beverage: to ensure tanks and silos don't overfill, which could lead to a spillage and product waste
• Chemical: to prevent run drys or dangerous chemical reactions
• Oil and gas: to prevent an overflow, which could result in environmental damage
• Water and water treatment: to prevent flooding and water waste or to ensure water supplies are at a constant level
• Manufacturing: to ensure that machines don't overload, which could lead to equipment breakdown
• Pharmaceutical: to prevent product waste
• Steel production: to prevent ladle spillage
