Pressure regulators are closed-looped devices that maintain a constant, steady pressure within a system. The traditional option, analog, has its perks, as does its counterpart, the digital controller. This straightforward explanation will detail the differences between digital vs. analog control in proportional applications and highlight some of the benefits to the newer, modern digital device. […]
Digital flow meters are high-tech devices with a customizable, touch screen interface. They’re used for gauging and displaying qualities like mass flow rate, volumetric flow rate, gas temperature, atmospheric pressure, and gas pressure. The components of a digital flow meter—anemometers, thermistors, gauge pressure transducers, and absolute pressure transducers—all serve unique roles in its operation. The […]
Control valves are used to control the flow of fluids or gasses within a closed system. They get directions from a controller that sends signals to the valve, so it knows the set point it must maintain. This allows for the direct control of the rate of flow within the system. Control of the flow […]
Proportional control valves have been since the 80s and are increasing in their popularity. They are replacing servo valves in lots of applications. This is due in part to the cost of a hydraulic proportional valve being 50% of the cost of a servo valve of the same size. Servo valves continue to be used […]
Measurement of flow, be it a gas or liquid, is a critical parameter in many processes. In most operations, it’s important to know that the right material is in the right place at the right time. Some applications need the ability to conduct accurate flow measurements to ensure the quality of the product. Health and […]
