Introduction ▲ Flowmeter is a new type flowmeter with organic glass as the main body, which is used to measure the single-phase non pulsating flow of liquid or gas. It is characterized by beautiful appearance, light weight, not easy to crack, and long service life




Principle ▲ When the fluid flows through the tapered hole from bottom to top, a pressure difference is generated between the top and bottom of the float, and the float rises under this pressure difference. When the force that makes the float rise is equal to the combined force of gravity, buoyancy and viscosity, the float is in a balanced position. Therefore, there is a certain ratio between the flow through the flowmeter and the rise height of the float, that is, the flow area of the flowmeter. The position height of the float can be used as a flow measurement. The reading position of the flowmeter is shown in the figure below



When installing a ▲ flowmeter, the filler shall be taken out and vertically installed on the panel or pipe without vibration. The newly installed pipe shall be cleaned before the flowmeter is installed

▲ When the flowmeter is in use, slowly open the valve to full open, and then use the valve to adjust the flow




▲ Materials of parts and components of flowmeter: the main body is organic glass; Copper chrome plating of connector (stainless steel 304 is optional); Float agate ball or stainless steel, guide rod is stainless steel 316; The O-ring is silicone rubber




▲ The working pressure of the flowmeter is less than or equal to 1Mpa; Operating temperature ≤ 80 ℃




▲ Flow measurement unit involved: GPM=gallon/minute; LPM=L/min; GPH=gallons per hour; LPH=litres per hour; M3/h=cubic meter/hour;

(Unit conversion: 1 gallon (US)=3.785 liters; 1 cubic meter=1000 liters)
