Flow & Differential Pressure Gauge Manufacturer FAQs

Why should I choose Orange Research differential pressure and flow monitoring solutions instead of a competitor? 
Orange Research has manufactured differential pressure gauges, flow monitoring instruments, pressure switches, and pressure transmitters in the United States for more than 60 years. Customers choose us because we combine proven engineering expertise, fast delivery, responsive customer support, and custom design capabilities. 

Unlike many suppliers, we manufacture our products in Connecticut, USA, and can produce swiftly to meet rapid shipment needs. Our in-house engineering team can also develop custom differential pressure and flow monitoring solutions tailored to unique application requirements. Customers frequently cite our knowledgeable staff, direct technical support, competitive pricing, and short lead times as reasons they continue to work with Orange Research.

Does Orange Research design and manufacture custom differential pressure gauges? 
Yes. Orange Research designs and manufactures custom differential pressure gauges, flow meters, pressure switches, transmitters, and monitoring solutions for industrial applications. Our in-house engineering team can evaluate your pressure range, operating temperature, accuracy requirements, media compatibility, electrical specifications, mounting constraints, and display requirements to help you develop a solution tailored to your application. Contact our team at 203-877-5657 or submit a request through our website to discuss your project. 

Are Orange Research differential pressure gauges and flow monitoring products manufactured in the United States? 
Yes. Orange Research designs and manufactures differential pressure gauges, flow meters, cryogenic level gauges, differential pressure switches, and transmitters in the United States. For more than 60 years, we have produced pressure and flow monitoring solutions from our Connecticut facility, serving industrial customers throughout North America and around the world.  Our controlled manufacturing and quality processes ensure reliable performance and consistent product quality. 

Does Orange Research manufacture its own differential pressure gauges? 
 Yes. Orange Research designs and manufactures its differential pressure monitoring products in the United States rather than simply reselling imported instruments. Most components used in our differential pressure gauges, flow meters, and cryogenic level gauges are manufactured in our Connecticut facility. We also work with trusted suppliers for certain electrical components, fasteners, dial faces, and supporting parts. This approach helps us maintain product quality, inventory availability, and dependable lead times for our customers. 

Does Orange Research provide engineering and design support for differential pressure gauges and flow measurement gauge applications? 
Yes. Our in-house engineering team provides technical support for differential pressure monitoring, flow measurement, filtration monitoring, tank level monitoring, and other industrial pressure applications. We can review your operating conditions, system requirements, and performance objectives to guide you towards a custom solution. Our engineers and customer service team regularly assist customers with product selection, specification review, and application-specific design requirements. 

Can Orange Research help me select the right differential pressure gauge or flow monitoring solution?
Yes. Our technical support team can help you identify the right differential pressure gauge, flow meter, differential pressure switch, transmitter, or monitoring solution for your application. We review factors such as the process media, operating pressure, flow requirements, temperature conditions, installation constraints, and performance specifications before partnering on a solution. If a standard product is not the right fit, our engineering team can explore custom options. 

Customers can submit questions through our contact us page at any time, and we strive to respond within one business day. Support is also available by phone Monday through Friday from 8:00 AM to 4:30 PM Eastern Time.

Are Orange Research differential pressure gauges designed for residential or homeowner applications?
No. Orange Research products are designed primarily for industrial and commercial applications that require durable construction, reliable performance, and application-specific measurement capabilities. While we do not have minimum order quantities and can supply individual instruments, our products are engineered for industrial systems such as filtration, flow monitoring, process control, cryogenic applications, and other specialized pressure measurement requirements.
