Vortex - Model FM03 Type -Flow Meter

• Since there are no displacement parts, the flow meter meter has excellent reliability and durability, and there is no installation position error.
• The structure is simple (the flow direction of the fluid only includes cylindrical objects and vortex detectors), which ensures low pressure loss and low leakage. Additionally, the sensor does not come into contact with the fluid flowing through the channel, making it ideal for monitoring various liquid processes.
• According to your needs, two body materials (PPS and PFA) can be selected.
• All specifications (CE Mark certified)
• Since Teflon is the material of the entire body part and no O-ring is used, the FM03 series Karman vortex flowmeter is the best choice for monitoring liquid flow in semiconductor manufacturing processes.

When the medium flows through the Braff body at a certain speed, alternately arranged vortex bands are generated behind the sides of the Braff body, called "von Kalman vortices". Since eddy currents are alternately generated on both sides of the vortex generator, pressure pulsations are created on both sides of the generator, which can cause alternating stress to the detector. The piezoelectric element encapsulated in the detection probe body generates an alternating charge signal with the same frequency as the vortex under the action of alternating stress. The frequency of these pulses is proportional to the flow rate. After the signal is amplified by the preamplifier, it is sent to the intelligent flow accumulator for processing

In a certain range of Reynolds number (2×10^4~7×10^6), the relationship between the vortex release frequency, fluid velocity and the width of the vortex generator facing the flow surface can be expressed by the following formula:^[3]
