Orange Research Inc. products

Our flow meters are designed for those applications where a rotameter is not appropriate. Consider the inherent problems of rotameters - they are difficult to read, especially with dirty or opaque fluids, have low pressure ratings and allow vertical orientation only. Orange Research low flow flow meter models have large dials with bold markings and characters that are easy to read from a distance, handle high line pressures and can be mounted in any orientation.

Our flow meters are designed for those applications where a rotameter is not appropriate. Consider the inherent problems of rotameters - they are difficult to read, especially with dirty or opaque fluids, have low pressure ratings and allow vertical orientation only. Now consider that Orange Research high pressure flow meters have large dials with bold markings and characters that are easy to read from a distance, handle high line pressures and can be mounted in any orientation.

Our new, fully integrated differential pressure flow meters are compact and rugged, with directly connected, large throated, non-clogging flow nozzles. This unique design reduces size and cost while minimizing errors and leaks. Simply select the flow rate and material, and you`re set. There is no need to choose a primary flow element, a differential pressure gauge, and then piping. Ordering, installation, and maintenance is simplified with Orange Research differential pressure flow meters. Everything is in one compact package.

Orange Research has been a supplier of PVC flow meters and PVC switches for water and corrosive liquids applications for over 20 years. Now we’ve expanded the line to add more features. The primary wetted parts are PVC, Teflon for compatibility with water and liquid chemicals. They’re perfect for difficult environments where aluminum, stainless steel or brass is not appropriate.

Our 30000 Series fixed set-point flow switches have factory-preset settings. The many features and the adjustability found on our other models have been designed out.
