The microbridge mass airflow sensor operates on the theory of heat transfer. Massairflow is directed across the surface of the sensing elements. Output voltage varies in proportion to the mass air or other gas flow through the inlet and outlet portsof the package. The specially designed housing precisely directs and controlsthe airflow across the microstructure sense element. Mechanical design of thepackage allows it to be easily mounted to printed circuit boards.The microbridge mass airflow sensor has a unique silicon chip based on advanced microstructure technology. It consists of a thin-film, thermally isolated bridge structure containing heater and temperature sensing elements. The bridge structure provides a sensitive and fast response to the flow of air or other gas over the chip. Dual sensing elements positioned on both sides of a central heating element indicate flow direction as well as flow rate. Laser trimmed thick film and thin film resistors provide consistent interchangeability from one device to the next.The microbridge mass airflow sensor uses temperature-sensitive resistors deposited within a thin film of silicon nitride. They are suspended in the form of two bridges over an etched cavity in the silicon, shown below. The chip is located in a precisely dimensioned airflow channel to provide a repeatable flow response. Highly effective thermal isolation for theheater and sensing resistors is attained by etching the cavity space beneath the flow sensor bridges. The small size and thermal isolation of the microbridge mass airflow sensor are responsible for the extremely fast response and high sensitivity to flows.Dual Wheatstone bridges control airflow measurement — one provides closed loop heater control, the other contains the dual sensing elements. The heater circuit minimizes shift due to ambient temperature changes by providing an output proportional to mass flow. The circuitkeeps the heater temperature at a constant differential (160°C) above ambient air temperature which is sensed by a heat-sunk resistor on the chip. The ratiometric voltage output of the device corresponds to the differential voltage across the Wheatstone bridge circuit.

Measuring range h: 0.04 up to 1.3 m with integrated ultrasonic level sensor, expandable with external pressure sensor up to 0-3.5 m Data storage: 2 MB (Q-Eye MII, Q-Eye MDS-5), 2 GB (Q-Eye PSC) Data transmission: integrated GSM/GPRS modem as option for Q-Eye MII external GSM/GPRS modem as option for Q-Eye MDS-5 Q-Eye MII (mobile measurement) The strength of Q-Eye MII lies in mobile applications. The long lifetime of approx. 90 days with a measuring interval of 5 minutes, as well as the small and robust housing make it perfect for temporary measurements. In addition to water level and flow, the quality of signal, battery voltage and calculated velocity are also stored in the data logger. An impulse output provides the necessary signal to a sampler. With the optional connectable pressure sensor, the water level can be collected redundantly. The measuring range can be upgraded up to 3.5m. All connection cables are provided with water tight plugs, which makes mounting or changing of battery in field easy. The display, which is activated with a magnetic switch, shows the active measuring values and informs about the status of the measuring device. With laptop and Software Q-Vision Setup, all parameters are entered and the measured values are read out. Q-Eye MDS5 (stationary measurement). Our discharg measuring system type Q-Eye MDS5 is composed of two individual hardware components the ultrasonic Doppler sensor with measuring signal converter "Q-Eye", as well as the reliable SEBA data logger type "MDS-5" for continuous data storage of for example flow, level and battery voltage. If requested, further digital or analogue sensors (e.g. multi- parameter probe MPS-D3) can be connected. Flow measure- ments in small streams or canals up to approximately 4-5 m width are the ideal application for our Q-Eye MDS5. Due to its very low energy consumption this instrument does not need an external power supply! With a measuring interval of 15 minutes in combination with a 100 Ah battery, a durability of 3 months can be achieved without problems! Good news also for users who are already working with SEBA MDS data loggers: existing operating and evaluation software WEbdien, DEMASvis, DEMASdb or the SEBA HDA can be used continuously without further investments.

Reduce lost production time and maximize your line's efficiency The Micro-Flow Sensor is a flow detecting device, used within a semi or fully automated metering process, to detect whether a material has been dispensed. The Micro-Flow Sensor does not control the metering volume. It is used particularly when handling unfilled grease with NLGI class 1 to 3, high viscosity oils or silicone-oils. The Micro-Flow Sensor can be adapted to the DOPAG Micro and Mini metering valves as well as to the 419 range of metering valves.
