Abstract

The invention provides a mass-flow-meter calibration detection device. The mass-flow-meter calibration detection device comprises a calibration solution output unit, a calibration pipe, a metering unit and fixing base frames for fixing the calibration pipe. The calibration solution output unit is connected with the calibration pipe, and the calibration pipe is connected with the metering unit. According to the mass-flow-meter calibration detection device, a constant-current stable-voltage tank is arranged at the front end of a calibration mass flow meter, and can provide a constant-current stable-voltage calibration medium solution, it is achieved that mass flow meters can output stable phase difference signals in the calibration metering process, and meanwhile the calibration mass flow meter is installed at a U-shaped pipe and calibrated; the calibration metering accuracy of mass-flow-meter products can be increased, the metering accuracy of a whole calibration device system can also be increased, and the defect that the calibration accuracy of a product cannot be increased through an existing calibration device is overcome.
