Product Introduction



Working principle


Double-deck Tank Leakage Detecting Instrument consist of GH-SLI Console and SYW-E Sensor. It can make a distinction between water and oil, enjoys real - time monitoring function.


This instrument designed for detecting water and oil between the two layers of double-deck tank. When there are lakegae between the two layer of tank, the SYW-E Sensor will detetect it and give singal to GH-SLI Console, the console will giving an audible and visual alarm through software calculation.

Users can take measures to deal with the leakage according the alarm, to avoid the safety hidden trouble and environmental pollution.


The leakage detecting instrument complete with switch output signal, can realize interlocking control afterconnect with other equipments.




1. This sensor is equipped with fault self-checking function, free from artificial fault test;

2. This sensor is equipped with oil-water differentiation function, which can provide basis for judging leakage of inner tank or leakage of outer tank;

3. This sensor is equipped with flange, placed firmly and installed easily;

4. This sensor adopts RS485 communication and reduces wiring cost;

5. This sensor adopts oil resistant and corrosion resistant cable, which is durable in use.



Technical parameters

1. Response time<1S

2. Working voltage: +5~12VDC

3. Working current: <10mA

4. Working temperature: -40℃~+60℃

5. Precision of leakage liquid level detection: <3mm

6. Explosion-proof sign: ExiaIIBT4G


Guihe SYW-E leak detection sensor consists of piezoelectric crystal, oscillating circuit, rectifier circuit and microprocessor etc. Piezoelectric crystal and oscillating circuit generate square wave with a certain frequency, and the square wave frequency is the natural frequency of vibration of piezoelectric crystal, belonging to the physical property of sensor. When oscillator plate of sensor gets in touch with liquid, vibration frequency will change significantly; this frequency change is collected and perceived by microprocessor inside the shell, and the microprocessor and peripheral circuit judge that the contact liquid is oil or water according to the change of frequency, and hereby infer that inner leakage or outer leakage happens to double-compartment tank. This sensor is not disturbed by the liquid structure, turbulence, agitation, vibration and other circumstances, and not limited by the light, with impact resistance, which can adapt to more complex scene environment. In addition, compared with leak detection sensors with other principles, this sensor is featured by stronger anti-interference ability.


Precautions for us

1. SYW-E leak detection sensor and GH-SLI double-layer tank leak detector shall be used together composed of intrinsically safe explosion-proof system, which can be applicable to hazardous area.

2. GH-SLI double-layer tank leak detector must be placed in non-hazardous area without any explosive gas mixture. SYW-E leak detection sensor belongs to intrinsically safe products and guard grating of associated apparatus shall be installed when connected with GH-SLI double-layer tank leak detector; its connecting cable is four-core shielded wire (with insulating sheath), and its shielding layer and ground terminal of GH-SLI double-layer tank leak detector are earthed in safe location.

3. Influence of electromagnetic interference shall be eliminated as far as possible during cable wiring and distributed capacitance of cable shall be less than 1.0µF and distributed inductance less than 1mH.

4. User shall not arbitrarily replace components and parts of sensor, which will affect explosion-proof performance of product, and shall solve fault in operation together with product manufacture so as to completely eradicate accident.

5. Installation, use and maintenance of product shall be in conformity with product manual, GB3836-2010 explosion-proof criteria, gasoline station design and construction specification and national standards; in addition, the product must be equipped with electrical apparatus for explosive atmospheres and installed by unit with use and maintenance qualification.
