Description

The V*0FC series Gas Mass Flow Controllers /Meters (hereinafter, referred to as MFC/MFM) were designed to calculate the flow of gases by measuring the differential pressure, pressure and temperature of the laminar flow element. This measurement method combines the features of inherent Linearity, good repeatability, high accuracy as well as little temperature drift. In addition, preheating is not needed. The MFC/MFM are able to provide simultaneously four different parameters, including instantaneous flow, accumulative flow, temperature and absolute pressure which can all been displayed and output at the same time. The conventional thermal technology is able to measure the mass flow of the gases directly without temperature compensation; however, the productions utilizing the thermal technology have inevitable defects, such as thermal drift and slow response due to the long-term heating. The MFC/MFM Suitabledifferential pressure technology can start to work the minute they get electric power with no preheating, which is previously unattainable. They have hardly zero point or temperature drift and are able to give a prompt response. Nowadays, several leading manufacturers of thermal flow meters launch upon developing differential pressure mass flow meters. Sailsors Instruments Ltd. has over *0 years of combined experience in researching, developing and manufacturing differential pressure mass flow devices for a wide variety of precison gas flow monitoring, measuring and controlling needs. According to market demand, Sailsors issues the V*0FC series as popular products with the features of high accuracy and multi-functions.
