The Sensyflow FMT700-P is a thermal mass flowmeter for direct air mass flow measurement without pressure or temperature compensation. It comprises a sensor installed in an ABB measuring section with inlet and outlet sections and a flow conditioner, available in nominal diameters DN 25 to DN 200. The separate 19-inch plug-in transmitter provides 0 to 10 V and 0/4 to 20 mA analog outputs, an RS232 serial interface, and supports up to two sensors. The sensor has an IP54 and NEMA 12 rating, operates on 115 or 230 V AC, and delivers ≤ ±1.0% measuring accuracy with ≤ ±0.25% repeatability and a response time of ≤ 12 ms. Wetted components are anodized aluminum or stainless steel, and the medium temperature range is −25 to 80 °C. It is used in automotive test benches and R&D applications.
The measuring system comprises a flowmeter sensor (measuring tube), a measuring section and a supply / evaluation unit. The FMT700-P Compact has an integrated transmitter.
The sensor is designed as a measuring tube and accommodates the measuring elements. The meter tube is available in six nominal diameters ranging from DN 25 to DN 200 and is installed in the measuring section by using quick-clamping connectors.
The measuring section consists of inlet and outlet sections of the appropriate size and of an air filter or flow conditioner which can be connected – e.g. to an air duct – via the connection piece on the suction side.
The Sensyflow FMT700-P Compact can simultaneously operate one analog output (current 0 / 4 to 20 mA or voltage 0 to 5 / 10 V), one digital output (frequency, pulse, alarm) and a serial RS232 interface.
The supply / evaluation unit is available as a 19” plug-in version or as a desktop unit. It provides the power supply for the sensor and converts its flow-dependent current signal into standard analog mass flow signals. The unit with a 6-digit display is suitable for all measuring tubes and automatically identifies the appropriate nominal diameter. Further diagnostic functions allow simple and safe operation.
