Abstract

The utility model discloses a reservoir water level measuring device which comprises a pressure transmitter. The pressure transmitter is arranged above a reservoir and connected with a power source through a wire, a pressure guiding pipe is further arranged below the pressure transmitter, the lower end of the pressure guiding pipe is inserted into the portion below the water level of the reservoir, the upper end of the pressure guiding pipe is provided with a pressure sensor, and the pressure sensor is fixed at the lower end of the pressure transmitter. Water pressure is guided out of the water face through the pressure guiding pipe so that the pressure can be measured by the pressure sensor arranged on the water face. The common pressure sensor is adopted, so that the manufacturing cost is low. The service life of the reservoir water level measuring device reaches up to 10 years. Due to the fact that the pressure sensor is located above the water face and is not in contact with the water, the pressure sensor is not placed in water for a long time and can not be corroded by objects in the water, the phenomenon of scaling is avoided and the pressure sensor does not need to be maintained in the process of use.

Description

Measuring device for level of reservoir

Technical field

The utility model relates to the level measuring technical field, particularly a kind of measuring device for level of reservoir.

Background technology

" flood retention retaining and regulate the water conservancy structure of current; can be used to irrigate; generating; control flood and breed fish; it refers in the gully or the narrow orifice place in river builds the artificial lake that barrage forms; after reservoir builds up that reservoir is general is interpreted as, can play flood control, catchwork irrigation, supply water, generating, the effect such as breed fish, sometimes natural lake is also referred to as reservoir, the water level of reservoir affects near the life that relies on the majority that reservoir makes a living it, therefore, the Measurement accuracy of reservoir level also becomes a requisite part, existing level measurement device is put into water with the pressure transducer probe, by measuring water to the pressure variation of sensor probe, obtain the measurement data of the variation of water level, because damaging after corrosion and the fouling, its serviceable life is lower, and need to often check easily for pressure transducer like this, time and effort consuming has improved maintenance cost.

Summary of the invention

In order to overcome defects, the utility model provides a kind of and can not be corroded, the measuring device for level of reservoir of fouling.

The utility model for the technical scheme that solves its technical matters and adopt is: a kind of measuring device for level of reservoir, comprise a pressure unit, described pressure unit is located at the reservoir top, pressure unit is by a wire connecting power, the below of described pressure unit also is provided with a connecting pipe, the water level below of reservoir is inserted in the lower end of described connecting pipe, and a pressure transducer is installed in the upper end of connecting pipe, and described pressure transducer is fixed on the pressure unit lower end.

As further improvement of the utility model, described connecting pipe also is connected with the pressure-sustaining gas ingress pipe, on the described pressure-sustaining gas ingress pipe constant pressure valve is installed.

As further improvement of the utility model, described pressure transducer is piezoelectric pressure indicator.

The beneficial effects of the utility model are: the utility model is slept hydraulic pressure everywhere by connecting pipe, pressure can be installed in the pressure transducer of the water surface and measure, the utility model adopts the usual pressure sensor, its low cost, and the life-span can reach more than 10 years because sensor places side waterborne, do not contact with water, therefore can the situation of fouling can not occur yet because of placing for a long time water by the corrosion of the material of water, do not need in the use procedure to safeguard.
