Description

Technical Field

[0001] The utility model belongs to the technical field of flow meters, and in particular relates to a bidirectional flow meter. Background Art

[0002] A flow meter is a meter that indicates the measured flow rate and / or the total amount of fluid in a selected time interval. In simple terms, it is a meter used to measure the flow rate of fluid in a pipeline or open channel.

[0003] Flow meters are classified by medium: liquid flow meters and gas flow meters. There are many types of flow meters that are usually used for liquid flow and gas flow. Among them, probe flow meters are more common. Probe flow meters use the Pitot tube principle to measure the total pressure and static pressure of the fluid in the center of the fluid delivery pipeline, and calculate the volume flow rate and mass flow rate of the fluid from the total pressure and static pressure of the fluid in the fluid delivery pipeline.

[0004] In the prior art, when the probe flow meter is used, the probe flow sensor is inserted into the fluid delivery pipeline, so that the axes of the total pressure hole and the static pressure hole are in the same straight line with the axis of the fluid delivery pipeline, the total pressure hole faces the direction of fluid flow, and the static pressure hole faces the direction of fluid flow. The probe flow sensor transmits the measured total pressure and static pressure of the fluid in the center of the pipeline to the differential pressure transmitter, and the differential pressure transmitter combines the fluid temperature, density, pipeline cross-section and other parameters to calculate the volume flow and mass flow of the fluid.

[0005] The probe flowmeter disclosed in the above-mentioned prior art measures the flow rate of the fluid in the fluid conveying pipeline in a single direction. If the fluid conveying pipeline sometimes conveys fluid in a forward direction and sometimes conveys fluid in a reverse direction due to industrial needs, the probe flowmeter in the above-mentioned prior art can only measure the flow rate of the fluid flowing in the forward direction in the fluid conveying pipeline, and cannot measure the flow rate of the fluid flowing in the reverse direction in the pipeline.

[0006] When the probe flow meter disclosed in the above-mentioned prior art is in use, if flow monitoring is performed in an outdoor environment without a stable power supply, it cannot be guaranteed that the flow meter can adapt to various environmental conditions to ensure accurate flow measurement. For example, when the flow meter is installed and measured for field operations and field environmental protection, the flow meter cannot be installed in time or used to upload and back up data.

[0007] In view of the above factors, a bidirectional flowmeter is specially designed to realize bidirectional fluid detection and measure the flow parameters of fluids, gases and other substances. The annular chamber throttling device adopts a different form. The annular chamber throttling device is set as a conical channel or the annular chamber throttling device is set as an annular channel. When in use, it does not affect the fluid flow in the forward / reverse direction of the measurement pipeline. Utility Model Content
