Working principle Variable area flowmeter using a float in a tapered tube made of special plastic materials. The fluid flows up through the tapered tube forcing the float to a position with sufficient free area to enable the flow to pass. This free area is related to the flow rate, the weight of the float and the density and viscosity of the fluid. The pressure drop across the flowmeter remains constant over the entire flow range, since it is related to the fluid density and the float weight and dimensions. Flow indication is achieved since the area of flow increases as the flow rate...

Plastic tube flowmeters Series PT/PS Flow ranges Flow scales Model Nº Flow scales with PTFE float fits special float to reach higher flow rate For PT / PS series, all plastic loaded floats are in PVDF+Pb, except for tube models PS-316-M014 ... M050, in PVC+Pb Flow scales Model Nº

Limit switches Adjustable limit switch PT-AMR Bi-stable SPST reed switch, actuated by a magnet inside the float and mounted in a PVC enclosure: - PT-AMR1 ... 2: 1 ... 2 adjustable reed switches  Standard: normally opened (NO) switches. Normally closed (NC) reed switches are available on request.  Operation: the standard contact is normally opened. That means: - Maximum flow: on increasing flow, the contact closes when the float reaches the height of the alarm sensor. It remains closed while the float is above the sensor. It opens again when the flow rate decreases and the float returns...
