Wind Measurement: A unique folded-path, low power sonic anemometer operates on the principle that the speed of the wind affects the time it takes for sound to travel from one point to a second point. If the sound is traveling in the direction of the wind, then the transit time is decreased. If the sound is traveling in a direction opposite the wind, then the transit time is increased. The wind sensor has no moving parts, which makes it maintenance free. The measurement range for wind speed is from 0 to 112 mph (0 to 50 ms) and for wind direction from 0 to 360°.Barometric Pressure, Temperature, and Humidity Module : Barometric pressure, temperature, and humidity sensors are housed in a powder-coated metal radiation shield. Barometric pressure is measured with a stable transducer using nano-technology, yielding a linear and repeatable sensor with low hysteresis. The piezoresistive pressure sensor module is mounted on a small electronic circuit board. A micro controller controls the operation of the sensor and the data interface. The micro controller polls the pressure sensor module once per second for the barometric and ambient temperature. The raw readings are temperature corrected by the micro controller. Temperature measurement uses a precision triple-element thermistor. This provides highly accurate and stable readings. Humidity is measured with a capacitive polymer sensor. This construction provides excellent resistance to wetting, dust, dirt, oils, and common environmental chemicals.

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.

Aqua Profiler makes monitoring flow in natural streams, concrete lined channels and partially filled pipes very easy. It is able to measure flow in harsh and difficult hydraulic conditions. This lightweight and compact system uses HydroVision's proven acoustic profiling technology to measure the flow, velocity and water level. The system is designed to measure both the vector and magnitude (using twin velocity beams) of individual cells (up to 128) to account for velocity variations within the flow, and obtain the flow profile. A third vertical beam is used to measure water level and combined with the velocity profile, calculates flow most accurately. The robust HDA-Pro in combination with the software "AquaProfiler mobile" provide all necessary information to the user at any time. The Aqua Profiler measures the position and velocity of the particle, and hence establishes the fluid flow component in the given space point. The basic feature of the Acoustic Flow Profile is the ability to establish the velocity in many separate space points along the measurement axis and develop the flow profile. Alternatively to the complete flow profile, a single spot velocity in a specific cell can also be determined.

The microprocessor measures the output of the internal compass and then corrects wind direction data for the orientation of the sensor. The output of the wind direction is relative to magnetic north. A user-programmable value of magnetic declination may be entered through terminal mode to enable output relative to True north rather than magnetic north.

The chemical oxygen demand, ST-COD value (ST = small scale sealed tube), of water as determined by this dichromate method can be considered as an estimate of the theoretical oxygen demand, i.e. the amount of oxygen consumed in total chemical oxidation of the organic constituents present in the water.

Respirometric methods provide direct measurement of the oxygen consumed by microorganisms from an air or oxygen-enriched environment in a closed vessel under conditions of constant temperature and agitation. Carbon dioxide produced metabolically by the bacteria is chemically bound by the potassium hydroxide solution contained in the seal cup in the bottle. The result is a pressure drop in the system, which is directly proportional to the BOD value and is measured by the Lovibond BOD sensor. The BOD level is then displayed directly in mg/l. The BOD values are stored in the sensor memory and can be called up on the large-format display at any time without the need for time-consuming conversion using factors. This means that test series that end on a Sunday can be evaluated during the following week without any problem. The measurement period is user-selectable between 1 and 28 days to suit the application. While short measurement periods are useful for scientific applications, standard BOD measurements typically extend over a period of 5 days – and manometric determination of OECD, for example, generally takes place over a period of 28 days.
