Valve Well Type Natural Gas Leakage Detector
1.Product Overview
Discovery - CS1:
Using the technique of Time-Delayed Laser Absorption Spectroscopy
(TDLAS), by measuring the intensity changes of the laser before and
after passing through the detection area, the concentration of
natural gas leakage can be calculated. It has the monitoring
function of environmental temperature, humidity and pressure, which
is used to compensate and correct the measurement results to reduce
the interference of environmental factors on the detection.
2.Product Features
Discovery - CS1:
(1) High anti-interference ability, unaffected by water vapor and
other gases, only responding to methane.
(2) Long sensor lifespan, high stability (lasting over 10 years).
(3) Uses wireless communication, strong communication capability,
not limited by communication distance.
(4) Overall IP67 waterproof design, suitable for humid and
prone-to-leakage underground environments.
(5) Overall intrinsically safe design, stable and reliable.
(6) Suitable for explosive gas mixtures of Group IIA to IIC, T1 to
T4 temperature classes in Zone 1 and Zone 2 explosive hazardous
areas.
(7) Can be connected to vibration signals, long-distance monitoring
of leakage.
(8) Detects water level information, clarifies the working status
of the equipment.
3. Application
Discovery - CS1:
It is mainly applied to the monitoring and early warning of
flammable gas leakage in underground pipeline networks of urban
lifelines. It can be widely used in underground valve wells and
various confined spaces, such as urban gas, long-distance
pipelines, comprehensive pipe galleries, petroleum, chemical,
steel, fire protection, power, environmental protection, and
pharmaceutical industries. It is suitable for explosive gas
mixtures in Zone 1 and Zone 2 of explosion hazard areas with
temperature groups IIA to IIC and T1 to T4.
