ULTRASONIC FLOW SENSOR

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.
