Change from one to two columns Thermal Mass Flowmeter Sensyflow FMT4-VTS, FMT4-VTCS /4-6.22-EN General information. Principle of operation and construction Change from one to two columns The devices of the Sensyflow FMT4-series operate according to the thermal measuring principle of a hot film anemometer. This measuring method determines the gas mass flow directly. Taking the standard density of the gases into consideration, the standard volume flow rate can be displayed without additional pressure and temperature compensation. Sensyflow FMT4-VTS is used in the field of process engineering and Sensyflow FMT4-VTCS in the food and beverage industry for flow measurement of gases and gas mixtures. The measuring systems of the FMT4 series are made up of a transmitter, flowmeter sensor and a pipe component. The transmitter directly delivers an electrically isolated /4 2 ma output signal. The flowmeter sensor is designed as flange-mounted and is installed in the pipe component in a defined way. The pipe component is available in nominal diameters ranging from DN 25 DN 2 ( 8 ) and in various designs. It is also possible to install the flowmeter sensor in square ducts or pipes of any diameter by using a weld-on adapter. q m R MG I H R H Physics of measurement Thermal flow metering procedures use different ways to evaluate the flow dependent cooling of a heated resistor as measuring signal. In a hotfilm anemometer with temperature difference control, the heated platinum resistor is maintained at a constant overtemperature in relation to an unheated platinum sensor inside the gas flow. The heating power required for maintaining the overtemperature depends directly on the flow rate and the material properties of the gas. With a known (and constant) gas composition the mass-flow can be determined by electronically evaluating the heater current/mass-flow curve without additional pressure and temperature compensation. Together with the standard density of the gas this results directly in the standard volume flow. Considering the high measuring range dynamics up to :5, an accuracy smaller than % of the measuring value is achieved. Fig. : q m R MG R H I H Analog measuring principle Gas mass-flow Gas temperature measuring resistor Heating resistor Actuel value of heater G825 The gas stream flows past two temperature-sensitive resistors R H and R MG which are part of an electrical bridge circuit. Due to the chosen resistance ratio R H < R MG, R H is heated by the current I H, and R MG adopts the same temperature as the gas. The current I H is preset by the electronic control circuit to produce a constant temperature difference between the heated resistor R H and the temperature of the gas. The electrical power generated with resistor R H exactly compensates its loss of heat to the gas flow. As this loss of heat is dependent on the number of particles which collide with the surface of resistor R H, I H represents a measure of the mass flow rate. Typical applications Gas flow measurement in the chemical and processing industries, Compressed air balances, Gas burner control, Gas measurement for air separation systems, Activation air measurement in sewage plants, Hydrogen measurement in processes. 3

The bottom edge of the spigot nut indicates the current sensor unit position (see Detail A, sensor unit is in exchange position). Only when the measuring position 5 OPEN - MESSEN (lower stop of the spigot nut) is reached, the sensor elements are placed exactly in the center of the pipe and exact measurement is ensured. IMPORTANT (NOTE) For integrated hot tap fitting in wafer flange design DN 65, use connection flange PN6 with 4 screw holes on the process side. Wafer flange versions 2 8" only for connection flange ASME B6.5 Cl.5. It is recommended to use the hot tap fitting for measurements in main conduits (e.g. compressed air systems) or for measuring points which otherwise require rinsing prior to removing the flowmeter sensor. As a rule, hot tap fittings should be preferred for all systems where, otherwise, the entire system or parts of it must be switched off to replace a flowmeter sensor. 2

For combinations of inlet run disturbances, e. g. valve and reducer, you must always consider the longer inlet run length. In confined spaces at the mounting location the outlet run length can be shortened to 3 x D. The reduction of the minimum inlet run length, however, will impact on the achievable accuracy. High repeatability of the measuring value is still provided. Under certain circumstances, special calibration can be performed for insufficient steadying lengths. For this purpose and in individual cases consulting is necessary. For gases with extremely low density (hydrogen, helium) the steadying lengths must be doubled. 2
