Flow Meters, Switches,
& Transmitters

 

Flow meters, flow switches and flow transmitters from Orange Research provide accuracy and reliability in affordable, rugged packages. These industrial quality flow devices combine modern technology and materials with a familiar easy-to-read pointer and dial gauge. A magnetic movement allows flow sensing at high line pressures and operation in any orientation. For more than 50 years, Orange Research has manufactured the highest quality flow gauge, flow meter and flow measurement products.

Fixed Orifice, Variable Area, and DP Flow Meters & Gauges

Our fixed-orifice flow meters are best for low-flow applications. They are able to measure down to 2 GPH, so small changes in flow rate can be seen and users alerted. Because these flow meters use a fixed orifice, users must consider two factors: abrasive fluids and fluids that may leave deposits. This can affect accuracy over time by changing the size of the orifice.

Our variable-area flow meters use a larger orifice and a movable flow cone, which reduces the potential for clogging. We offer specially designed flow meter cones for use under harsh conditions where dirt and debris may be present, such as in wastewater or construction site environments. The variable-area sensor in these flow meters allows for readings on a linear scale, often preferred over square root meters.

Our differential pressure flow meter models have directly connected, large-throated, non-clogging flow nozzles. The flow nozzle design is a long life, wear-resistant element that provides many years of service. Our differential pressure flow meters are known worldwide as the rugged, "install them and forget them" type of flow meters.

Our 30000 Series is a fixed set-point flow switch. Their compact size and basic profile results in low-cost flow switches that can be mounted where space is limited. This makes them popular for OEM applications where simple flow switch actuation is required.
