The report states that with the increasing adoption of industrial automation, technological advancements in liquid level sensors, and increased usage in the energy and power sectors, it will drive the growth of the liquid level sensor market. However, insufficient accuracy and precision of liquid level sensors may hinder market growth.
In terms of type, in 2018, the contact sensor market accounted for nearly two-thirds of the sensor market share, and it is expected to contribute its share during the forecast period, due to the accuracy provided for liquid level measurement and the reliability of traditional liquid level sensors. However, the report states that due to technological advancements and the industry’s rapid adoption of deployment in harsh environments, it is expected that the growth rate of the non-contact segment market will reach 8.2% from 2019 to 2026.
From an application perspective, the sub market of point monitoring has a market share in the liquid level sensor market, contributing nearly three-fifths of the market share in 2018, and is expected to maintain a dominant position throughout the entire forecast period. Due to cost-effectiveness and multi-purpose applications in the commercial, industrial, and residential sectors, it is expected that the compound annual growth rate of this segmented market will reach a fast compound annual growth rate of 8.0% from 2019 to 2026.
From a regional perspective, the market share of the Asia Pacific region accounted for nearly half of the liquid level sensor market in 2018 and is expected to contribute significantly during the forecast period. In addition, from 2019 to 2026, the compound annual growth rate of this segmented market is expected to reach 7.6%, with North America continuing to occupy the second largest market share.
What is a liquid level sensor?
A liquid level sensor is a device used to monitor, maintain, and measure the level of liquids (sometimes solids). Once the liquid level is detected, the sensor will convert the sensed data into an electrical signal. Liquid level sensors are mainly used in the manufacturing and automotive industries, but they can also be found in many household appliances, such as ice makers in refrigerators.
There are two main categories of liquid level sensors: point level sensors and continuous level sensors. The point sensor is designed to indicate whether the liquid has reached a specific point in the container. On the other hand, continuous liquid level sensors are used for liquid level measurement. Liquid level sensors can be further divided into invasive and non-contact sensors. Intrusive sensors come into direct contact with the measured substance, while non-contact sensors use sound or microwave.
Liquid level sensors are mainly divided into two categories: point level sensors and continuous level sensors. The point sensor is designed to indicate whether the liquid has reached a specific point in the container; Continuous liquid level sensors are used for providing liquid level measurements. Liquid level sensors can be divided into invasive sensors and non-contact sensors. Intrusive sensors come into direct contact with the measured substance, while non-contact sensors use sound waves or microwaves.
There are many different types of point level sensors, but they are all invasive. One of the basic point level sensors is the “float switch”. When the liquid level in the container rises or falls, it will force the switch to open or close the circuit.
Among them, the optical liquid level sensor consists of an infrared emitter and a photodiode. As a photoelectric proximity sensor, they detect the presence of liquid by measuring the amount of infrared light reflected back to the photodiode. A capacitive liquid level sensor measures the change in capacitance (the ability to store charges) to determine the liquid level in the tank. The tuning fork type liquid level sensor uses the difference between pressure and vibration to measure the liquid level.
