Ideal mass-stream flow meters.Based on a simple and robust through-flow design, the Mass-Stream series from Bronkhorst UK presents no obstructions to the flow path, has no moving parts Moving parts are the components of a device that undergo continuous or frequent motion, most commonly rotation. "Parts" only include the mechanical components which does not include fuel, or any other gas or liquid. and features very low-to-ultra low pressure drop across the instrument. These features make the Mass-Stream ideal for the mass flow measurement of dirty gases, wet gases and even a combination of the two. Furthermore, the minimal pressure drop prevents harmful liquid drop-out from condensing con·dense v. con·densed, con·dens·ing, con·dens·es v.tr. 1. To reduce the volume or compass of. 2.

Typical flow measuring applications for the Mass-Stream series include biogas bi·o·gas n. A mixture of methane and carbon dioxide produced by bacterial degradation of organic matter and used as a fuel. biogas Noun gaseous fuel produced by the fermentation of organic waste from land-fill sites and digesters, WF6, SiCl4 and other condensing gases, dirty exhaust gases from combustion processes, carrier gases for particle analysers and humidified powder carrier gases for pharmaceutical research. In addition, the straightforward design can be applied to such cost-sensitive applications as consumption metering for accounting or internal billing purposes, medical gas monitoring, burner ratio control, air flow control in paint spray lines, multiple gas mixing and gas generators. Suitable for a wide range of gases and with standard pipe fittings between 1/8" OD and 20mm, the Mass-Stream D-62XX series can be calibrated cal·i·brate tr.v. cal·i·brat·ed, cal·i·brat·ing, cal·i·brates 1. To check, adjust, or determine by comparison with a standard (the graduations of a quantitative measuring instrument): between flows of 0.25 and 6000 Ln/min air-equivalent; it has a standard turn-down of 20:1, although this can be higher on application. When configured as a mass flow controller A mass flow controller (MFC) is a device used to measure and control the flow of gases. A mass flow controller is designed and calibrated to control a specific type of gas at a particular range of flow rates. , a direct acting proportional solenoid valve is integrated directly onto the base-block, for regulating flows up to 500 Ln/min. Options include an integrated flow display on all models, a range of readout (1) A small display device that typically shows only a few digits or a couple of lines of data. (2) Any display screen or panel. systems for analogue instruments, and digital versions providing fieldbus interfaces. One possible configuration is the combination of an external potentiometer, on-board PID (1) (Process IDentifier) A temporary number assigned by the operating system to a process or service. (2) (Proportional-Integral-Derivative) The most common control methodology in process control. control and integral flow rate indication; whilst still providing an output signal for data logging, such an instrument represents a standalone solution, without the need for an external set-point signal.
