Stable development and people's lives it is stable, played an important role in town development and safe operation is ensured.With cities and towns
Develop rapidly, urban drainage pipe network system becomes increasingly complex, is more and more huger, operational management to drainage pipeline networks, maintenance pipe
Reason, emergent flood control and science decision etc. propose higher and higher requirement.Underground pipe network water level information is the important ginseng of pipe network again
Number.So it is particularly important for the water level detecting of underground pipe network.Ultrasonic material level meter is mainly straight using ultrasonic sensor
Connect to surface of material and launch ultrasonic pulse signal, acoustic signals reflect in surface of material, and reflected signal is connect by sensor
Receive.Instrument measurement simultaneously calculates transmitting with receiving the time difference t of pulse signal.The speed of sound wave is C, sensor emission end face diaphragm
Distance D between surface of material：D=C*t/2；The distance E of known slack tank, then now liquid level L=E-D；The speed C of sound wave by
The influence of temperature changes and changed(m/s), C is the velocity of sound, and T is temperature.T often changes 1 DEG C, and C about becomes
Change 0.607m/s.Built-in temperature sensor is needed in ultrasonic sensor, compensates the sonic velocity change caused by temperature changes.It is existing
The pressure type of ultrasonic level gage, condenser type, the traditional measurement mode such as float-type, it is rotten to there is winding, blocking, leakage, medium
Lose, safeguard the shortcomings of inconvenient.
The content of the invention
The technical problems to be solved by the invention are：There is provided and surpass for the integration of underground pipe network water level non-contact measurement
Sonic liquid-level meter, the Integral ultrasonic liquid level gauge that this kind is used for underground pipe network water level non-contact measurement are easily installed maintenance,
Using for a long time still can keep measurement accurate.
Solve the technical problem, the technical scheme is that：One for underground pipe network water level non-contact measurement
Body ultrasonic level gage, it includes meter housing, display panel, bezel plate, waterproof bracket, sensor, nut, connection
Bar, cover sheet, wiring board and junction block, described meter housing, display panel, bezel plate, cover sheet, wiring board and
Junction block is respectively positioned on the top of connecting rod, and described sensor and nut are located at the bottom of connecting rod, and described nut is close to even
Extension bar, described wiring board and junction block are located in meter housing, and described display panel is located at the side of meter housing, described instrument
Table front shroud is adjacent with display panel, and the top of described waterproof bracket has the groove being adapted with meter housing bottom, described
Waterproof bracket in the middle part of have with connecting rod be adapted circular hole, described connecting rod pass through waterproof bracket circular hole, it is described
Meter housing is placed on waterproof bracket.
The bottom of described waterproof bracket circular hole is provided with rubber ring.
The side of described wiring board is provided with the cover sheet that area is more than wiring board.
The present invention is used for structure as the Integral ultrasonic liquid level gauge use of underground pipe network water level non-contact measurement,
Maintenance is easily installed, for a long time using measurement still can be kept accurate.
