• Flow meter with laminarizer or flow straightener Flow-Trak is an economical solution to reduce the straight section of the pipeline before and after the flow meter in conditions of lack of space. The flow transformation element removes distortions of the velocity profile, turbulence and temperature unevenness in the gas flow. A uniform flow rate profile is achieved by two perforated stainless steel plates. The front plate of the laminarizer is clamped between two flanges on the pipe 40 at a pressure of up to 25 atm and 1/8" sealing rings (flanges and seals of the supplier). The mounting bolts of the flanges center the screen in the center. The rectifier can reduce the size of the straight section in front of the flow meter to 1-3 diameters after standard sources of turbulence, such as bends, constrictions, pipeline extensions, the presence of a valve, pump and others. The Flow-Trak can be purchased separately, or it can be purchased together with the Sierra heat flow meter. In this case, the flow meter is calibrated together with the rectifier. There is extensive experience of application with flowmeters 780S, 780S-UHP and 240 vortex mass multiparameter.

• The Chlorine-Trak 760S flow meter has been designed specifically as a cost-effective solution for measuring the mass flow rate of chlorine in the wastewater treatment process.
