We met with an original equipment manufacturer (OEM) last year, who was working on a new design for rooftop air handling equipment. Part of the their design utilized water flow for cooling in a loop.
Low or no-flow conditions can cause major damage to expensive pumps, motors, and other equipment, which could result in extensive downtime and repair costs. In order to prevent this, the customer needed an inexpensive, but reliable and robust method for proving water flow. Continue reading “Proving Water Flow in Rooftop Air Handlers”
Vane or paddle flow switches are used to initiate high or low flow alarms. A common application is as a low flow alarm for shut-down of a system for protection of the components from damage. Often these are used in cooling lines, oil lines, or monitoring other fluid flows that are critical for the system to operate. Continue reading “Custom Vanes for the V4 Vane Operated Flow Switch”
