Description

A kind of multiple flow passages ultrasonic wave gas meter
Technical field
The utility model relates to a kind of gas meter, flow meter, especially a kind of multiple flow passages ultrasonic wave gas meter.
Background technique
Ultrasonic wave gas meter measures gas flow rate using time difference method principle, suitable in a fluid by measurement ultrasonic signal The difference of speed when propagating with adverse current is flowed to reflect the flow velocity of fluid.Because the time difference method velocity of sound with fluid temperature variations bring error compared with Small, accuracy is higher, and application is wide.
Single channel, which is generally used, in the ultrasonic wave gas meter used at present carries out gas flow measurement, this single channel Ultrasonic wave gas meter haves the defects that certain: i.e. when the measurement range of the metering module in ultrasonic wave runner is bigger, measurement Accuracy is lower, and error is larger, when the measurement range of the metering module in ultrasonic wave runner is smaller, can not be suitable for big stream Amount field.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of the utility model is to provide a kind of multiple flow passages ultrasonic wave gas Table.
To achieve the goals above, a kind of multiple flow passages ultrasonic wave gas meter designed by the utility model, including watchcase, institute Watchcase is stated equipped with air inlet and gas outlet, the watchcase is interior to be equipped with valve, and the valve is connected with air inlet, the watchcase Interior to be equipped with outlet pipe and multiple ultrasonic wave runners, the outlet pipe is connected to gas outlet fixation, the multiple ultrasonic wave Runner is connected with outlet pipe, and metering module, the metering module and interconnecting module are equipped in each ultrasonic wave runner Electrical connection, the interconnecting module are electrically connected with display screen.
Further, the outlet pipe includes tube body, the tube body be equipped with an outlet communications ports and it is multiple into Gas communications ports, the outlet communications ports are connected to gas outlet fixation, and the air inlet communications ports and ultrasonic wave runner are one by one Corresponding connection.
Further, the air inlet communications ports include seal receptacle and be connected to seat, the connection seat through seal receptacle and with pipe Body is connected, and the ultrasonic wave runner is equipped with connector, and the seal receptacle is inserted in connector and close with connector inner wall Envelope connection.
Further, the cross section of the connector is circle.
Further, the ultrasonic wave runner is laterally arranged.
Further, the quantity of the ultrasonic wave runner is 2 or 3 or 4.
Compared with prior art, the utility model has the beneficial effects that multiple ultrasonic wave runners are set in watchcase, and It is respectively provided with metering module in each ultrasonic wave runner, makes to reduce by the gas flow in each ultrasonic wave runner, to improve The data of the accuracy of measurement of metering module, metering module measurement are transferred on interconnecting module, the comprehensive multiple meters of interconnecting module It measures the measurement data of module and is transferred on display screen and shown, using multiple each supersonic flows of metering module independent measurement Gas flow in road, can not only increase the measurement range of flow, and can guarantee the accuracy of measurement, and error is small, moreover it is possible to Ensure accurately measuring for tiny flow quantity, while meeting industrial circle big flow and need that the small flow of domestic environments uses combustion gas It asks.
Detailed description of the invention
