Gradually thicken, influenceed when incrustation scale thickness to certain degree will be produced on the measuring accuracy of table, especially calorimeter, due to stream
The water temperature crossed is higher, and high temperature can accelerate the formation of incrustation scale, therefore the situation of generation deterioration in accuracy can be earlier.
The method for suppressing and slowing down incrustation scale formation by positive electric field is to solve the problems, such as one of main method of incrustation scale at present, its
Principle is, by placing positive electrode inside pipeline, positive electric field to be internally formed in pipeline, is repelled each other by the general character, so as to suppress band just
The calcium ions and magnesium ions of electric charge are separated out and form incrustation scale.Existing such solution needs to place positive electrode inside pipeline, and just
The modes of emplacement of electrode is usually two metal electrodes of placement in pipeline, respectively close to water inlet end and water side, this metal electricity
Pole is connected to inside gauge outfit by wire, and positive electric field is provided by the circuit inside gauge outfit.Simultaneously two can be also set inside pipeline
Ultrasonic transducer, for measuring the time and tide time difference in pipeline.Due to needing to increase a pair of metal electrodes, therefore use this
The defect of class method is to increase pipeline configuration or transducer architecture design and the complexity and cost of manufacture.
The content of the invention

Gauge transducer also possesses the circuit of scale-deposit-preventing function, so as to reduce the complexity and cost of global design.
In order to achieve the above objects and other related objects, the present invention provides a kind of water resistant dirt electricity for ultrasonic flowmeter
Road, including the ultrasonic transducer in fluid line is arranged on, ceramic chips are provided with the ultrasonic transducer, it is described
Ceramic chips are provided with the first pin, the second pin for being grounded for launching or receiving pulse signal, and it is also wrapped
First switch module and second switch module are included, when ultrasonic transducer is in measurement, first switch module connection the
One pin and the signal end for launching or receiving pulse, the second switch module connection second pin and ground；In ultrasonic wave transducer
When device is in idle condition, the first switch module connects the first pin and positive electrode.
Preferably, when ultrasonic transducer is in idle condition, second switch module connection second pin with just
Electrode.
Preferably, the first switch module, second switch module are transistor or relay.
Preferably, the first switch module, second switch module are also connected with a controller, and the controller is used to control
Make the first switch module, second switch module action.
As described above, the water resistant dirt circuit for ultrasonic flowmeter of the invention has the advantages that：The circuit
On circuit boards directly set two switch modules, when in working order, switch module connect signal end with measure,
Under idle condition, switch module can be such that the pin of chip is connected with positive electrode, and the pin or shell of such chip just can be used to shape
Into positive electric field, therefore also so can effectively simplify circuit structure just without setting metal electrode in pipeline again, while reduction is changed
Can device be designed and manufactured as this.
