Problems solved by technology
[0004] First of all, the radar liquid level sensor needs to be installed penetratingly on the deck, and there are protrusions on the deck, which will affect the stacking of goods on the deck
[0005] Second, for liquid tanks that pass through multiple deck layers, if the existing radar liquid level sensor is only installed on the uppermost deck, it will be difficult to accurately measure the liquid level remotely, and the lower deck will be sensitive to the radar. The detection of the type liquid level sensor causes interference, resulting in deviations in the measurement results or even impossible measurement

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] see Figure 1-Figure 7 , a side-mounted radar liquid level telemetry device for a liquid tank, which includes a radar liquid level sensor 1, a waveguide cable 2, a waveguide cable fixing member 5, a bilge fixing seat 6 and fixing screws in the oil tank comprehensive layout.
[0031] Such as figure 2 As shown, a radar liquid level sensor 1 is arranged on the top of the oil tank, which is connected to the oil tank through the short connection pipe 4 and the connecting flange set on the top of the oil tank. The short connection tube 4 adopts 114x5.0 seamless steel pipe. The interior of the seamless steel pipe is a waveguide hard rod 3 (with bend), connect the radar liquid level sensor 1 and the waveguide cable 2 in the cabin. The remaining space inside the seamless steel pipe is filled with PTFE seals to ensure sealing and no leaka...

The invention relates to a side installation type radar liquid level remote surveying device of a liquid tank and belongs to the technical field of ship liquid tank liquid level surveying. The side installation type radar liquid level remote surveying device of the liquid tank is characterized in that one or more decks are arranged inside the liquid tank, the liquid tank is divided into two or more liquid storage spaces vertically, and every two adjacent liquid storage spaces are communicated; a radar type liquid level sensor (1) is installed on the side wall of the top liquid storage space through a short installation pipe (4), a wave guide hard rod (3) with a 90 degrees bent corner is arranged inside the short installation pipe (4), the wave guide hard rod (3) is connected with a wave guide cable (2), the wave guide cable (2) passes downward through openings of the decks in the vertical direction, and the bottom end of the wave guide cable (2) is fixed at the tank bottom; the wave guide cable (2) detects the liquid level height through liquid level oscillation.
Description
technical field [0001] The invention relates to a side-mounted radar liquid level telemetry device for a liquid tank, belonging to the technical field of remote measurement of the liquid level of a ship liquid tank. Background technique [0002] The liquid level remote measurement system is an important part of the ship's whole ship monitoring and alarm system. Conventional liquid level telemetry systems generally include: piezoelectric, bubble, and radar. [0003] For liquid tanks with high viscosity liquids such as fuel tanks and diesel tanks, radar liquid level remote measurement devices are usually used. The existing radar liquid level telemetry devices are generally top-mounted, and the radar liquid level sensor is usually penetratingly installed on the deck, and the height of the liquid level is remotely measured by vertically emitting radar waves downward. This radar liquid level sensor has the following disadvantages during use: [0004] First of all, the radar li...
