Float Level Sensors are used to measure liquid levels, a common application of which is in water tanks, oil tanks, chemical tanks and so on. The QT114A-ISG is a kind of float level sensor which can be used in various applications. This article will discuss the application field and working principle of QT114A-ISG float level sensor.
The diagram below shows a typical installation of the QT114A-ISG float level sensor.

First of all, the application of QT114A-ISG is quite wide. It can be applied in food and beverage, chemicals and petroleum, water treatment, and industrial applications. The float level sensor is reliable and accurate – measuring liquid levels up to 0.6 inches and providing accuracy within +/- 0.1 inches. It can be installed in steel, plastic, or glass tanks, as it is corrosion-resistant.
The QT114A-ISG float level sensor works on the reverse-acting principle. The sensor consists of a float float level sensor and a stem extend into the tank. A magnet on the float interacts with the top of the stem, which is filled with an electrical conductor. The electrical conductor is connected to a switch. When the float reaches a certain level in the tank, the magnet interacts with the conductor, which enables the switch to close, thus indicating the presence of liquid in the tank.
The QT114A-ISG float level sensor is also installed in applications that require more accuracy than the reverse-acting models. It is equipped with a sensing rod that extends further down into the tank than the magnets on the float. This sensing rod contains two electrical conductors which interact with the magnets when the level of liquid reaches the desired level. The two conductors interact with each other, which activates the switch, thus indicating the presence of liquid in the tank.
The installation of QT114A-ISG float level sensor is easy. There are only two steps involved in the installation. Firstly, the float must be installed onto the stem and tightened down securely. Secondly, the conductor and switch must be attached to the stem. After the installation is completed, the float level sensor is ready to accurately measure liquid levels up to 0.6 inches.
In summary, the QT114A-ISG float level sensor is a reliable and accurate tool that can be used in various applications. It is easy to install and can measure liquid levels up to 0.6 inches with accuracy within +/- 0.1 inches. It works on the reverse-acting principle and is resistant to corrosion. Plus, it is also equipped with a sensing rod with two electrical conductors, thus providing more accuracy than the reverse-acting models.
