AI Technical Summary

Technical Problem

When performing zero-point correction, common mass flowmeters cause stress to occur inside the flow tube due to temperature changes, which cannot be released quickly, resulting in errors in the oscillation curve, making the zero-point state and corresponding data inaccurate, affecting the accuracy of the measured values.

Method used

The heating device is used to preheat, heat and insulate the flow tube and the conveying medium, and release the internal stress of the flow tube through the folding pipe section and the connecting parts to realize automatic zero-point compensation of the flowmeter.

Benefits of technology

Through the combination of the heating device and the folding pipe section, the internal stress of the flow tube is quickly released, ensuring the zero-point state of the flowmeter and the accuracy of the data, thereby ensuring the accuracy of the actual flow measured value of the conveying medium.

Abstract

The utility model discloses a zero-point automatic compensation mass flow meter, which comprises a flow pipe, an oscillating device, a medium conveying pipe, a zero-point automatic compensation device, a zero-point automatic compensation device, a zero-point automatic compensation device and a zero-point automatic compensation device, and is characterized in that the flow pipe is connected with an adapting pipe and an oscillating device; the heating device is embedded in the folding pipe section; the triangular outer tube is arranged on the flow tube in a sleeving manner; and the sensor is arranged on the triangular outer tube and is used for sensing the oscillating flow tube. Compared with a common mass flow meter, the mass flow meter has the advantages that the flow pipe and a conveying medium are preheated through the heating device, and internal stress of the flow pipe is automatically and quickly released in cooperation with the folding pipe section, so that zero-point automatic compensation of the flow meter is realized, and the accuracy of flow meter data at the zero point of the flow meter in a static and natural state of the conveying medium is ensured; and therefore, the accuracy of the measured flow value of the subsequently flowing conveying medium is ensured. The multi-layer folding pipe is designed to be matched with the connecting piece, and leakage-free and sealed installation of the heating device is guaranteed.
