Percolating medium is mostly dry gas, and gas mass flow gauge is indispensable, and high-precision gas mass flowmenter is expensive,
In gas flow experiment, if misoperation in experiment, the hydraulic oil in triaxial cell will break through heat-shrink tube barrier, penetrate into
Sample, into the gas piping connected with sample end face, and under the sweeping along of gases at high pressure, inflow gas mass flowmenter, gently
Person can cause gas mass flow meter to measure data wander, influence measurement accuracy, and severe one can damage gas mass flow gauge, for
Gas piping oil inlet is damaged the problem of mass flowmenter, and current common processing method is clear after gas mass flow gauge oil inlet
Wash, but without more effective precautionary measures.
Therefore the utility model provides a kind of laboratory air pipeline oil inlet monitoring locking warning system, can be effectively sharp
And have in the infrared optocoupler of flute profile oil droplet by when photosignal change, monitoring locking and alarm during realizing pipeline oil inlet,
Prevent oil droplet from entering gas mass flow gauge, damage gas mass flow gauge.
