Differential Pressure Gauge Selection Guide – Features & Models

What is a Differential Pressure Gauge?

A differential pressure gauge measures the difference in pressure between two points in a system. Unlike standard pressure gauges that measure pressure at a single point, DP gauges display the pressure drop across equipment like filters, pumps, or flow elements, helping monitor performance, detect clogs, and ensure systems run efficiently.

Using a differential pressure gauge offers several benefits, including improved system efficiency, early fault detection, and reduced maintenance costs all crucial for keeping industrial operations running smoothly. Learn more about the advantages of differential pressure monitoring.

How to Select the Right Differential Pressure Gauge

Choosing the right DP gauge for your industrial application ensures accurate measurements, reliable performance, and long-term durability. When selecting a differential pressure gauge, key factors to consider include:

• Pressure Range: The gauge should cover your system’s operating pressures without exceeding maximum limits.
• Material Compatibility: Select materials that are compatible with the type of gas or liquid you are measuring to prevent corrosion or damage.
• Process Conditions: Consider temperature extremes, vibration, and other environmental factors that may impact DP gauge performance.
• Mounting and Connection Style: Choose the right configuration – panel mount or inline, for easier installation and visibility.
• Application Type: Whether you are measuring flow, monitoring filter conditions, or tracking liquid levels, select the gauge that is designed for the task.

Frequently Asked Questions

 
What types of differential pressure gauges are there?
There are many types of DP gauges, each designed based on the fluid type, the application, installation requirements and environmental conditions. Orange Research offers standard and custom models, explosion proof units, mini gauges, and are generally meant for higher pressure systems that require an extra rugged design.

What are differential pressure gauges used for?
Differential pressure gauges, also known as DP gauges, display the pressure differential between two points. They can measure pressure before and after a key component – such as a filter, heat exchanger, or valve, while also being popular in cryogenic tank level or dp flow measurements. They can indicate problem conditions based on changes in this pressure difference.

Can I buy a customized gauge?
Absolutely! Orange Research offers a wide variety of models that suit many standard application needs, but we can also manufacture custom gauges based on pressure, temperature, electrical and material requirements, as well as to meet industry standards. Gauge dial faces can also be custom produced with logos, colored arcs, and a wide selection of measurement units.

Can I adjust a differential pressure gauge switch on a gauge?
Yes, Orange Research’s DP gauges allow users to field adjust the switch. This allows the customer to tailor the switch settings to their needs, even if the conditions change after initial installation, eliminating the need to replace an entire gauge unit. Read more on how to field adjust our differential pressure gauge switches.
