Product introduction: 

GH-SL Pipeline leakage detector is composed of a SYW-SL leakage detection sensor, GH-SL detecting controller and other related accessories,.The leakage detector have real-time monitoring function. It is specially designed for detecting water and oil between the pipeline interlayer .When leakage occurs between the pipeline interlayer , the leaked liquid will gravity to the bulk tank , the SYW-SL sensor who keep in the bulk tank can detect the leaked liquid and make the signal to GH-SL controller , the controller get the signal and make the lights and audio alarm .Users can make a timely response and take related measures to avoid potential safety hazards  and environmental pollution based on the alarm. 

The detector is equipped with switch value output signal ,so it can realize interlocking control with third-party equipment .

Product Features:

1,Running safety, stability, easy maintenance: sensor device is composed of liquid         float switch, with simple structure and stable running.

2,High sensitivity: response time is less than one second.

3,Less cost, high efficiency:one leakage detector can take six leakage

detection sensor, each leakage detection sensor can take four double-layer pipeline  and one manhole well.

4,Simple installation and wide application : it can be easily installed in a    gas station, oil depot and other regions.

5,Relay output port, can make the equipment chain control with a third party.

6,485 communication port can realize uploading function.

Install Leakage Detection Sensor:

1,Put the Leakage detection sensor vertical installed in  the fixed bolt of manhole well.

2,Connection pipe test ports and detection device ports with oil conduit,oil conduit need short enough to avoid bending.

3,Connect snorkel to his connection Port.Complete the snorkel connection,the specific location is : on the manhole well inner wall of oil tank , directly above 1m and vertical direction.

4,Installation,use and maintenance of detection sensor should also comply with the product manual,GB3836-2010 explosion-proof criteria,Design of automotive filling oil and gas,construction specifications and other national standards. It is only allowed to make the installation construction who have the qualification of explosion-proof electrical equipment installation.
