3. Đồng hồ đo lưu lượng hơi PF3W Riels
The digital flow switchPF3W is a vortex flowmeter, suitable for water, demineralized water, ethylene glycol and neutral fluids.
The setting and displaying the flow rate is read directly on the digital display.
Available in two versions for different applications, integrated display and wireless remote display.
When an elongated object (vortex generator) is located in the flow, are generated reverse swirl in the downstream side.
These vortices are stable under certain conditions and their frequency is proportional to the flow velocity, in accordance with the following formula: f = kx v.
f = frequency; v = speed; k = proportional constant (determined according to the size of the vortex generator, to form etc..).
Therefore, the flow rate can be measured by detecting this frequency.
PF3W PVC Digital flow switches for deionized water and chemicals. Flow rates up to 250 l/min.
