The Wyatt Engineering Venturi flow tubes & meters have a rich history as a reliable tool for measuring flow. By leveraging fundamental physical relationships between velocities and pressures within pipes, they offer a consistent and highly repeatable differential pressure signal that can be customized for various applications.
The Wyatt Engineering Venturi Flow Tubes serve as primary flow elements that utilize the "Venturi Effect" to generate a difference in pressure within a closed pipe. These flow elements are versatile, capable of measuring various types of fluids, including both liquids and gases, and have a rich history of applications.
The Venturi Effect refers to the decrease in fluid pressure that occurs when the fluid is constricted through a throat section inside the pipe. This constriction leads to an increase in fluid velocity as it passes through a smaller cross-sectional area, thereby causing a reduction in pressure in line with Bernoulli's principle.
To measure the pressure difference, a Venturi flowmeter requires two pressure taps: one positioned on the inlet side before the restriction, and the other located in the throat section. Both taps are connected to a pressure gauge or transmitter to determine a △P pressure measurement. This resulting measurement is directly proportional to the square of the fluid velocity, allowing for accurate and reliable derivation of the flow rate. The design of the Venturi meter aims to maximize the differential pressure while minimizing the permanent pressure loss to the system.
In addition to Venturi flowmeters, Wyatt Engineering offers a range of other differential producing products, including flow nozzles, orifice plates, and metering and restriction runs.
