molbloc flow elements are connected to molbox RFM Flow Monitors with two pressure connections and one data line. molbox RFM Flow Monitors read calibration data off the molbloc EEPROM and measures molbloc upstream and downstream pressure with a built-in high accuracy Reference Pressure Transducers (RPTs). An ohmic measurement system reads the resistance of the molbloc platinum resistance thermometers from which molbloc temperature is calculated. Using the molbloc calibration data, pressures, temperature and gas properties stored in molbox RFM memory, the flow rate of the gas flowing through the molbloc is calculated. For molbloc-L flow elements, a microrange option is available to increase flow measurement resolution and accuracy under 10 % FS of the flow range.
molbox RFM and molbloc flow elements are useful in a variety of measurement, test and calibration applications in which highly accurate measurement of low gas flows is needed. molbox RFM is specifically designed for applications in which a highly compact presentation, great rangeability and reduced cost are the primary considerations. A second model, molbox1+, is available for applications in which lowest possible uncertainty is the top priority. To configure your mass flow calibration system, see the pages that follow to select the molbloc and pressure dependent calibrations to best cover your flow ranges and pressure conditions. molstic mounting systems and COMPASS® for molbox Flow calibration software are available to complete the system.
