FAQ:

Q: What is a portable flow meter?

A: Flow measurement type – momentum (velocity),volumetric or mass flow measurement Media – type of media (liquid,gas or slurry) and any special condition such as particulates in the media and viscosity of the media Media conditions – pressure and temperature of media and whether media conditions are likely to remain constant or vary

Q: What is universal flow meter?

A: Universal offers variable area flowmeters made of see-through plastic with metal or plastic port adapters that allow you to see your fluid. These are used for water, compressed air, dilute chemicals (such as those used in water treatment), and de-ionized water. Water. Ultrapure water.

Q: What is the flow rate of a meter?

A: Flow meters are either used to measure volume or mass. In a volumetric flow meter, the flow (Q) is equal to the cross-sectional area of the pipe (A), and the flowing fluid’s velocity (v): Q = A * v. In mass flow, the flow rate in a flow meter is given as ṁ = Q ∗ρ ( ρ here, is the fluid density and Q is the volumetric flow rate).

Q: What is an inline flow meter?

A: – FS10i Series. The compact FS10i Flow Meters are ideal for insertion or inline natural gas line sub-metering tasks. – ST51, ST51A Series. … – ST75, ST75A Series. … – ST80, ST80L Series. … – ST100A Series. …
