1 Sensyflow P Thermal air-mass flowmeter for test rigs and quality assurance 10/1-6.8 EN Direct mass flow measurement Wide measuring range (1:0) High measuring accuracy measuring deviation < 1 % of measured value Quick response time (T 6 = 1 ms) No moving parts Low pressure loss Easy handling Immediately ready for operation Defined installation in pipe Exchangeable transducer Arbitrary mounting orientation Low weight Expansive accessories/measuring sections Function and System Design Sensyflow P operates according to the principle of a hot-film anemometer. This measuring method enables the gas mass flow rate to be determined directly, without the need for pressure and temperature compensation. The Sensyflow P measuring system comprises of a transducer (measuring tube), a supply/evaluation unit and accessories. The transducer is designed as a measuring tube and incorporates the sensor unit and an electronic transmitter circuit. It is available in 6 nominal widths ranging from DN to DN 00 and is installed by quick-clamping connectors in the measuring section. The supply/evaluation unit is available as a 19" plug-in version or as a desktop unit. It provides the power supply for the transducer and converts its flow-dependent current signal into standard analog mass flow signals.

2 10/1-6.8 EN Function and System Design Example: oxygen at 0 C V = 10 m p = 1 bar ρ = 1, kg/m V = m p = bar ρ = 7,0 kg/m R T R h I h m = 1 kg m = 1 kg m ρ = m/v m = ρ V Most conventional flow meters determine volumetric flow rates. To achieve a mass flow signal, a volumetric flow meter needs pressure and temperature compensation. These corrective actions make measurement more expensive and reduce the ultimate accuracy of the measuring system. Sensyflow measuring systems provide the mass flow rate directly, i.e. without further measurement or correction. Example: If 10 m³ of oxygen is to be compressed from 1 to bar at a constant temperature, the volume or volume flow will change to m³, although the amount of substance and the mass are still the same (1 kg). In this case, a volumetric flow meter will only indicate 0 % of the original volume flow. As a result, a volume flow measurement for gases without correction of pressure and temperature is meaningless. The mass flow meter directly determines the mass per unit of time of a flowing medium; a measured value in kg/h is displayed. Parameters such as volumetric flow rate (referred to standard conditions) can be calculated directly from the standard density of the medium: q n = q m / ρ n e.g. in standard-m /h *) where q n = Volumetric flow rate referred to standard conditions (e.g. 0 C and 101 hpa) q m = Mass flow rate ρ n = Density referred to standard conditions (e.g. 0 C and 101 hpa) *) m /h -q n Measuring principle Sensyflow operates according to the principle of the hot-film anemometer. This method of measurement is based on the abstraction of heat from a heated body by an enveloping gas flow. The flow-dependent cooling impact is used as the measuring effect. The gas stream flows past two temperature-sensitive resistors R h and R T which are part of an electrical bridge circuit. Due to the chosen resistance ratio R h << R T, R h is heated by the current I h, and R T 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 the mass flow rate. Ordering information A measuring system consists of: Transducer, measuring pipe Power supply/evaluation unit Measuring section Cable for sensor Typical applications In a unique manner, Sensyflow P mass flow meters for air combine high accuracy, huge turn-down ratio and extremely fast response time. These features qualify them for the following application fields: Suction air measurements at combustion engines Test benches for turbo chargers Serial testing of flow dependent components like throttle valves, fans, air filters Quality assurance: reference unit for other flow meters Research & Development at universities and institutes Page of
