Vibration Tuning Fork Liquid Level Switch Applied in Alkali Absorption Tower - 1

Vibration Tuning Fork Liquid Level Switch Applied in Alkali Absorption Tower Alkali absorption tower is an important equipment specially used for industrial waste gas treatment, which is mainly composed of exhaust pipe, high-pressure blower, packed tower, corrosion-resistant circulating pump, alkali circulating pool and etc. The process is to suck the waste gas from the reactor to the bottom of the tower by negative pressure suction pipe and high-pressure blower, and the alkali liquor is lifted to the upper tower through circulating pump, so as to realize the gas-liquid countercurrent contact, acid-base neutralization and achieve the purpose of waste-gas treatment. The alkali liquor pumped into the circulating tower should reach a specified position, so the actual liquid level monitor is crucial to avoid overflow accident. It is usually required to match two types of liquid level sensors: continuous sensors to monitor the real time level, and point level switch sensors for high alarm control. Local level indication is an important measurement for many process control applications. It provides a reliable way to confirm the level height. Compared with radar level meter, ultrasonic level transmitter, RF admittance level meter, differential pressure transmitter, magnetic level indicators (MLI) has four key advantages — enhanced safety, maintenance, increased visibility and simplified installation — in which an MLI will actually reduce overall cost over time and improve functionality.

Vibration Tuning Fork Liquid Level Switch Applied in Alkali Absorption Tower - 2

jiwei — — Tuning fork liquid level switch vibrates at a specific frequency. When material touches the tines the vibration is attenuated. The unit detects this attenuation and outputs detection signals. Different from capacitive switch and RF admittance level switch, tuning fork liquid level switch can detect even physical property is changed, no need for initial adjustment and maintenance. Compared with float level switch, tuning fork liquid level switch is also not affected by liquid splashing. Ring-11 Liquid Level Switch is a highly reliable instrument for liquid level detection and...
