Instructions for use of the input level gauge

The input-type level meter offers several advantages, including high measurement accuracy, ease of installation, and the ability to transmit signals remotely. In contrast, the remote-controlled liquid level meter also provides high precision, easy setup, and remote control capabilities. It is resistant to corrosion from various media, suitable for explosive environments, and offers a moderate price. This type of instrument consists of a gas collection cylinder, pressure guide tubes, and a sensor. When the gas cylinder is submerged into the liquid being measured, the pressure exerted by the liquid compresses the air inside the cylinder. This pressure is then transmitted through the pressure guide tube to the sensitive component, allowing for accurate measurement of the liquid level. Importantly, the sensor does not come into direct contact with the measured medium.






By transmitting the pressure through the air guide tube, the sensor avoids direct contact with the measured medium, making it ideal for use in high-temperature and highly corrosive environments. This design effectively addresses challenges such as measuring levels in high-temperature liquids, corrosive substances, and wastewater. The input-type level meter is particularly well-suited for industries like metallurgy, power generation, papermaking, oil, and chemical production. It is a mature and reliable solution that is not affected by foaming, sedimentation, or turbidity in the medium. Additionally, it has no moving parts, making it easy to install and maintain. The input level gauge uses diffused silicon or ceramic sensitive components that rely on the piezoresistive effect to convert static pressure into electrical signals. After temperature compensation and linear correction, the device outputs a standard 4-20mA current signal. The sensor can be directly placed into the liquid, while the transmitter can be mounted using flanges or brackets, making it very convenient for installation and operation.
