Instruments are needed both in research, when elements of technology are being developed, experimental samples are created, and when developing equipment for the manufacture of small batches of products, and when creating industrial lines for mass production.
The main task of a flow meter is accurate determination the amount of substance (gas, liquid, vapor) passing through the device per unit time. One way to classify flow meters is by their upper limit of measurement. Devices can be divided into low, medium and large flows. The company "Sigma Plus Engineering" specializes in devices with a small flow range.
Flow meters by operating principle:
Thermal anemometer
Thermal with a sensor based on microelectromechanical systems (MEMS) technology.
Thermal capillary.
Coriolis
Ultrasonic
With variable pressure drop.
Turbine.
Brief overview:
Thermal flow meters provide highly accurate measurements of small gas flows, including minimal flows that cannot be measured in any other way. They can measure gas mass flow regardless of changes in operating conditions, maintaining performance and accuracy under high pressure or temperature conditions, with different types of gases.
Coriolis Flow meters provide highly accurate mass flow measurements, regardless of the characteristics of the substance being measured. They are capable of operating at elevated pressures, with corrosive gases and liquids, and also allow dosing.
The offered ultrasonic flow meters are designed to work with low liquid flow rates, Moreover, they do not depend on the physical properties of the working medium (density, temperature, viscosity, etc.).
Variable differential pressure flow meters provide flow measurement , comparable in accuracy to thermal flow meters. In this case, both volumetric and mass flow rates can be given. All of the above devices have a flow control function using a valve controlled by an electronic board.
Turbine flow meters for liquid media are proven instruments for measuring flow in a wide variety of operating conditions, including extreme temperatures, pressure, humidity, vibration and much more.
The Sigma Plus Engineering company not only offers innovative models with a long service life service life, but also provides additional services. Which include the provision of technical support, on-site visits by company employees for diagnostics, correct configuration and installation of devices, as well as warranty and post-warranty service.
