Problems solved by technology

When the flow field of the measured medium is unstable or there is interference noise, it will affect the accuracy of the measurement and affect the measurement results
Existing electronic metering instruments (such as gas meters) do not have measures to stabilize the flow of gas, resulting in unstable gas flow during the gas metering process, which easily leads to measurement deviation and interference from other factors, resulting in inaccurate measurement results

Abstract

The invention relates to the technical field of gas metering, and provides a flow stabilizer used for gas metering and a gas meter. The flow stabilizer comprises an upper shell, a lower shell connected with the upper shell detachably, an air inlet formed in the lower shell and an air outlet formed in the upper shell, an inner cavity is formed by assembling the upper shell and the lower shell, a flow stabilizer core is installed in the inner cavity, and comprises an inlet part, a flow stabilizing part and an arc face part, the flow stabilizing part is connected with the inlet part, and the arcface part is connected with the flow stabilizing part which comprises one or more flow stabilizing channels; circulating holes for airflow circulating are formed in the flow stabilizing channels, thearc face part comprises a flow guiding arc-shaped plate and a guiding arc-shaped plate, the flow guiding arc-shaped plate is in a U type, and gas which flows out of the flow stabilizing channels circles round along the inner wall of the flow guiding arc-shaped plate to stabilize the flowing speed of the gas to be metered. In the scheme, the invention further provides a gas meter with the flow stabilizer. The gas meter has the technical advantages that internal airflows are smooth and stable, interference is eliminated, and accordingly the metering accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of gas metering, in particular to a flow stabilizer for gas metering and a gas meter with the flow stabilizer. Background technique [0002] In the field of gas metering products, electronic metering instruments (such as thermal, ultrasonic and other electronic metering instruments) are measuring instruments that use metering electronics to measure the flow rate of the measured medium under standard conditions. The specific working principle is that when the measured medium flows through the metering Electronic parts, metering electronic parts convert the flow information of the measured medium into electronic signals for output. Electronic measuring instruments have certain requirements on the flow field and flow velocity of the measured medium when they are working. When the flow field of the measured medium is unstable or there is interference noise, it will affect the accuracy of the measurement and aff...
