Fluid level transmitter by plinth insert cylinder in refrigerant liquid directly contact, moistureproof Aviation Connector be retained in cylinder outside with
Plinth is combined to be fixed.
In above-mentioned technical proposal, plinth is connected by welding with cylinder；Liquid level sensor by fit sealing screw thread with
Plinth connects.
Thus, the utility model liquid level sensor is inserted directly in liquid level, and liquid level can be directly perceived rapidly, and signal
In feeding back to controller.There is advantages below relative to existing heat exchanger Liquid level mode：
（1）True liquid level can accurately be perceived.The position of plinth is located between tube sheet and liquid-distributing plate or supercooling gripper shoe,
The falsity water level that refrigerant is formed in the middle of cylinder can be avoided, the true liquid level in cylinder can be more accurately measured.
（2）Possible leak point is few, and system is safer.Plinth is connected by welding method with cylinder, liquid level sensor
Two parts by sealing screw thread be connected with plinth, the two possible leak points caused only are combined with plinth；And existing
In having liquid level cognitive method, two plinths and barrel soldering are needed, then liquid level sensor is again by sealing screw thread and two
Plinth connects respectively, has 4 possible leak points.So that leakage point is greatly decreased.
（3）The liquid level sensor is continous way fluid level transmitter, can accurately perceive the different liquid levels of heat exchanger.
