Please keep the distance between tank level probe, delivery pipe and suction pipe more than 1 meter. Otherwise, the oil flow will influence on the probe performance, even bend and damage the probe.

During the installation, it is important to adjust outlet direction of delivery pipe to opposite to the tank level gauge probe. 

Riser pipe must be welded vertical (vertical for horizontal not for manhole cover), insert into manhole cover but not more than 100mm. Internal wall of riser pipe must be smooth and no welding slag.  

Open a cable hole on the center of blind flange, fix G1/2 screw for cable pass and seal. Please see the picture at below.

All communication cables must go through protection steel pipe.

●When lying, protection steel pipe must be put under ground at least 300mm depth. Spacing distance between pipes must be at least 200mm.

●When lying, protection steel pipe must be put under ground at least 300mm depth. Spacing distance between pipes must be at least 200mm.

●Each cable of probe must be put in separate pipe.

●The cable from smart console to probe must be complete one, shouldn’t have any joint.

●For safety, we recommend use RVVP4×0.5 (or larger) shield cable and must accord with the requirement of capacitance per foot not more than 100pF, length of cable less than 300m. Shielding layer of cable from probe must be coupled with PE port of console, the shielding layer of cable in explosion proof junction box should be wrap up well by black tape,

●Protection steel pipe should be coupled with the earth system of gas station.

●The end of pipe which inside control room must be injected into silicon rubber, to ensure reliable sealing and avoid vapor going into room.

●AC220V/50Hz ±10%

●Power supply should be same phase and same position ( Zero wire left and live wire right, that is means face to socket, the left is zero wire, the right is live wire.

●Make sure reliable earth, and this earth should be same as office ground and tank area.

●It is forbidden that  connects to zero wire to  earth wire, do not mixed connection of zero wire and earth wire.

●There should have earth device or grounding sheet iron near console.

●This grounding device or grounding sheet iron should be truly connects to earth and keep equipotential with tank area. 

Safety warning:

To ensure normal work of gas station safety system, the anti-lightning system of gas station should be able to protect the whole ATGs system, and reserve earth port for ATGs system.

ATG system share the same earth connection of tank area.

The  communication cable tube of probe should not share the same tube with other cables.
