Float Level Meter

Name: Float Level Meter
Brand: Zhejiang Huaqiang Environmental Technology Co., Ltd.

The linkage float level meter is composed of a float and an insertion rod. It is installed on the top of the container through a connecting flange. The float floats on the liquid surface according to the principle of equal displaced liquid volume. When the liquid level of the container changes, the float also moves up and down. Due to magnetic action, the reed switch of the float level meter is magnetically attracted, converting the liquid level position into an electrical signal. The display instrument uses a digital display to show the actual position of the liquid, so as to achieve remote detection and control of the liquid level.

Applications of Float Level Meter

The float level meter is widely suitable for continuous measurement of the liquid level (interface) of high-temperature, high-pressure, viscous, dirty media, asphalt, wax-containing oil products, as well as flammable, explosive, and corrosive media.
It can be used for industrial measurement and control of liquid levels in various liquid tanks such as petroleum, chemical raw material storage, industrial processes, biochemistry, medicine, food and beverage, tank farm management, and gas station underground inventory.
It is also suitable for dam water level, reservoir water level monitoring, and sewage treatment, etc.
