Products & Solutions
Flocare has extended its range of flow rate indicators to include a Flow-Mon Miniflo unit for very low flows. Suitable for both liquid and gas applications, the Miniflo operates efficiently down to 50 cc/min and up to 5 litre a minute calibrated flow, with a maximum pressure tolerance of 13 MPa (130 bar).
The unit can have up to four signal switches, to a Zone 1 explosion-proof compliance if required, or the switches can be air operated for use in areas with extremely hazardous conditions.
Thirteen such air operated Miniflo units have been installed in a Russian refinery to control the flow of methanol at 12 MPa (120 bar).
Built-in features of the Flow-Mon range include inline design, a non-return feature and the advantage that it cannot be strained on cold start-up. As far as mechanical function is concerned, a fixed, tapered needle passing through an orifice in the face of a piston completely seals the port-to-port connection when the piston is seated. As flow commences, the piston is displaced against a 28 kPa differential spring and moves over the tapered section of the needle, thus permitting flow through the orifice. Only the needle taper configuration needs to be changed to accommodate any specified viscosity and maximum flow requirement, thus the full deflection of the unit can be used for all applications.
Piston movement is mechanically linked to a shaft, which is rotated to a degree exactly representing piston displacement and, therefore, flow through the orifice.
The shaft passes out of the unit wall into a switch box, where it carries a field-adjustable cam, to operate up to four micro-switches. A pointer on the shaft gives visual indication of flow.
Accuracy is not affected by orientation, so the unit can be mounted in any plane. For fine manual control of flow, a needle valve may be fitted to the outlet port, and this - in conjunction with the flow read out, provides a simple, accurate means of setting maximum flows through the line.
