Description
Delta Mobrey 131 Series Flow Switches is suitable for setpoints between 2.5 m/s and 12.5 m/s, with a max flow rate up to 17.5 m/s.
Vane Operated Flow Switch is designed to provide protection and control in ducted air systems in flammable atmospheres. Its main application is to detect air flow in HVAC systems located in harsh environments and/or hazardous area. The sensing element is a freely pivoted, counter-weighted vane which at its rest position lies at right angles to the direction of flow. The action of the flow is to pivot the vane and operate a microswitch via a dustproof seal.
The unit is manufactured, checked and supplied in accordance with our published specification, and when installed and used in normal or prescribed applications, with the lid in place and within the parameters set for mechanical and electrical performance, will not cause danger or hazard to life or limb.
