Featured Products
Positive Displacement (PD) Flow Meters
Positive displacement flow meters consist of a set of chambers or compartments that are filled with the fluid. Each time the fluid flows through the meter, the chambers fill to a certain volume. Once the chamber is full, it discharges the fluid and is refilled again for the next cycle. The key here is that each cycle corresponds to a known volume of fluid. The meter counts the number of these cycles, and based on the volume of each cycle, it calculates the flow rate. This process works well because the measurement is independent of factors like pressure and temperature, which can affect other types of flow meters.
Thermal Mass Flow Meters
Thermal mass flow meters provide direct mass flow measurements, making them highly accurate and efficient for gas flow applications. These meters are particularly useful in industries where precise gas flow measurement is critical, such as chemical processing, semiconductor manufacturing, and environmental monitoring. They are also known for their ability to operate without moving parts, which reduces maintenance requirements and enhances durability.
Coriolis Mass Flow Meters
A Coriolis flow meter is a highly accurate flow measurement device that measures the mass flow rate of a fluid directly, as opposed to measuring its volumetric flow rate. Unlike traditional flow meters, Coriolis meters do not rely on the fluid’s velocity or volumetric measurement; instead, they operate based on the principles of the Coriolis effect. This effect allows the Coriolis meter to measure the mass flow directly, making it especially useful in applications where density, viscosity, and temperature changes can impact measurement accuracy.
Magnetic Flow Meters
Among the different types of flow meters available, electromagnetic flow meters, or mag meters, stand out for their precision, reliability, and applicability in diverse settings. Since their invention in the 1950s, electromagnetic flow meters have become an industry standard for measuring the of conductive liquids. This technology’s non-intrusive nature, lack of moving parts, and broad compatibility with various liquid types make it a preferred choice in water treatment, chemical processing, food and beverage, and other industries.
Vortex Flow Meters
A vortex flow meter is a type of flow measurement instrument that measures the volumetric flow rate of fluids, such as liquids, gases, and steam, by detecting vortices shed from a bluff body inserted into the flow stream. The operation of a vortex flow meter is based on the phenomenon known as the von Kármán effect.When a fluid flows past a bluff body—a non-streamlined object—vortices are generated alternately on either side of the body. These vortices form a repeating pattern known as a Kármán vortex street. The frequency at which these vortices are shed is directly proportional to the velocity of the fluid flow.
Turbine Flow Meters
Turbine flow meters operate by detecting the velocity of fluid passing through a pipe, which causes a turbine or rotor within the flow tube to spin. The speed of the rotor’s rotation, which is directly proportional to the fluid’s flow rate, is measured by sensors (magnetic or optical) placed outside the tube. These sensors generate electrical pulses corresponding to the rotor’s revolutions, which are then converted into a readable flow rate by a flow transmitter
