Positive displacement flowmeters, also known as PD meters, measure volumes of fluid flowing through by counting repeatedly the filling and discharging of known fixed volumes. A typical positive displacement flowmeter comprises a chamber that obstructs the flow. Inside the chamber, a rotating\/reciprocating mechanical unit is placed to create fixed-volume discrete parcels from the passing fluid.<\/p>\n
Make a quick enquiry now..<\/strong><\/p>\n In the VFF the rotor is basically a disc shape with an annular groove on its underside capable of holding and transporting flow from the chamber inlet to the outlet. Some fluid is also transported in a cavity formed between the rotor outside wall and the chamber wall. A centre \u2018peg\u2019 under the rotor is constrained to run in a circular groove in the body. A web (or plate) in the body is engaged with a slot in the rotor and this modifies the rotation to that of an oscillation as flow passes. It is this oscillation that produces the compartmentation of the fluid into \u2018positively displaced pockets\u2019. The top of the rotor is equipped with a powerful magnet directly above the \u2018peg\u2019 that is on the underside and so this also has a circular path which allows it to engage and disengage a reed switch sensor located in the top cap above.<\/p>\n The MF (or Medium Flow) VFF covers flow rates up to 180 l\/hr. It was first provided in 1992. The MF30 was originally rated to 3.0 l\/min \u2013 hence MF30.<\/p>\n \u2666 Chemical Injection \u2666 Hydraulics \u2666 Wax Dispersant \u2666 Corrosion Inhbitor \u2666 Subsea Control fluid \u2666 PIB \u2666 Scale Inhibitor \u2666 Subsea flow \u2666 Ashalphtene Dispersant<\/p>\n","protected":false},"excerpt":{"rendered":" Positive displacement flowmeters, also known as PD meters, measure volumes of fluid flowing through by counting repeatedly the filling and discharging of known fixed volumes.
