首页>Liquid Level Measurement>Portable Ultrasonic Water Depth Meter The HS-PLD Intrinsically Safe Portable Liquid Level Meter is a specialized detection instrument for measuring the liquid level height in tank trucks or monitoring the liquid status at specific positions. It is used by oil depot management personnel to detect whether residual oil remains in tank trucks before they enter the tank farm for loading.
The equipment utilizes the ultrasonic echo ranging principle, employing advanced signal processing technology and high-speed signal processing chips. It overcomes the influence of container wall thickness, achieving true non-contact measurement of liquid height in sealed containers and detecting the presence of liquid at specific positions.
This product has been tested and certified by explosion-proof electrical product quality inspection institutions according to GB3836.1-2021, GB3836.4-2021, and GB3836.9-2021 standards. The explosion-proof marking is Ex ib IIB T4 Gb (main unit) and Ex mb II T6 Gb (probe unit). It is suitable for use in hazardous areas of Zone 1 and Zone 2 in factories containing explosive gas mixtures of Class IIA and IIB, Temperature Classes T1~T4.

Material of Measured Container (Oil Tank): The container wall where the ultrasonic probe is attached must be made of hard materials capable of transmitting signals effectively.
Examples: Carbon steel, stainless steel, various hard metals, fiberglass, epoxy resin, hard plastics, ceramics, glass, hard rubber, or other composite materials. The inner and outer surfaces of the container wall should be flat. If the container wall consists of multiple layers, the layers should be in close contact without bubbles or gas interlayers. Examples: vulcanized hard rubber lining, epoxy resin lining, stainless steel lining, titanium lining.
Wall Thickness of Measured Storage Tank (Container)：2-10mm；
Tank Type：Horizontal tanks；
Measured Medium：Gasoline, diesel, edible oil, etc.
