Profile: Orange Research, Inc. is a manufacturer of differential pressure gauges, switches and transmitters, flow meters and liquid level switches. Our products are used in applications such as monitoring filtration equipment, compressors and heat exchangers. Our flow devices indicate liquid flow rates and it can be supplied with reed switches & relays to initiate alarms & to activate other equipments or shut the system down. Our differential pressure gauges are designed to measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial. Our differential pressure transmitters includes microprocessor based instruments which are equipped with hall effect sensors that convert the gauges normal magnetic movements into electric signals and after processing the units provide analog and digital electronic output for remote location monitoring.
