Can a vortex flowmeter measure negative pressure?

Project Overview

　　Vortex flowmeter can measure negative pressure. Vortex flow meters can measure flow in both positive and negative pressure environments, but special considerations need to be taken when measuring negative pressure.

　　The working principle of a vortex flowmeter is to set up a vortex generator in the fluid to generate vortices around the blocking fluid, and then measure the frequency of the vortices to calculate the flow rate. This measurement method makes the vortex flowmeter suitable for measuring fluid flow in both positive and negative pressure environments.

　　When measuring negative pressure, the following points should be noted:

　　Negative pressure range: Vortex flowmeter can measure negative pressure, but the negative pressure value cannot exceed the limit of operating pressure, otherwise it may cause component failure and prevent normal use.

　　Application scenario: For example, the inlet duct of a fan or water pump is in a negative pressure environment, and the vortex flowmeter can work normally in this environment.

　　Attention: When using a vortex flowmeter to measure negative pressure, it is necessary to ensure that the negative pressure value in the pipeline is within the tolerance range of the instrument, and to pay attention to the installation and maintenance of the instrument to ensure accurate measurement.
