Open Area, Tunnel & Duct Air Flow Monitoring

The AV-622 is a single point, insertion, air velocity transmitter with user selectable 0-10vDC or 4-20mA outputs and 4 user selectable measurement ranges (0-4m/s, 0-8m/s, 0-16m/s or 0-32m/s). The unit requires a 12-35vDC power supply and has an Insertion length of up to 215mm and probe diameter of 19mm. A flange plate (DPA) is available for adjustment of the penetration depth. The unit has a built-in self test feature and the user can manually override the output to 0%, 50% or 100% of output range to aid commissioning. The enclosure has a snap-shut lid with an IP54 rating but can also be secured with screws to achieve a better IP65 rating.

The AV-622 replaces the AV-DSP air velocity transmitter

The AVT is an all in one air velocity and temperature transmitter suitable for HVAC applications and can be used for measuring air velocity, temperature and air volume in ventilation systems. Air volume is calculated from the air velocity and the duct diameters. Each unit has options of display and relay outputs in addition to the standard dual analogue outputs of 0-10V and 4-20mA for velocity and temperature.

A multi-point air velocity system using the PA267 differential pressure sensor and AV-EP or AV-MPS air velocity probes. This system can be used to ensure that recommended flow rates for public buildings and industrial plant are achieved. Suitable for flow ranges of 0 - 40m/s.

The DPT Flow is designed for centrifugal fans equiped with inlet rings. The air volume flow measurement is based on differential pressure value measured from the fan. Suitable for use with Flkt Woods, Rosenberg, Nicotra, Comefri, Ziehl, Ebm-Papst, Gebhardt branded centrifugal fans.

The MiniAir 6 is a vane anemometer for measuring the flow velocities of gases with a linear voltage output. The MiniAir 6 provides a 0-2V output relative to flow velocity ranges of up to 20m/s or 40m/s with Micro, Mini and Macro sized turbines. The units require a 6.5-26vDC power supply and the standard plastic, Aluminium probes can be used up to 80°C, with units available with separate electronics and Steel probes suitable for up to 250°C. The sensors are simple to install and can be easily integrate into a fixed system with other instrumentation including data loggers or displays.

The MiniAir 60 is a vane anemometer for measuring the flow velocities of gases with a linear frequency output. The MiniAir 60 provides a 0-4vDC/TTL output relative to flow velocity ranges of up to 20m/s or 40m/s with Micro, Mini and Macro sized turbines. The units require a 4.5-5.5vDC power supply and the standard plastic, Aluminium probes can be used up to 80°C, with units available with separate electronics and Steel probes suitable for up to 250°C. The sensors are simple to install and can be easily integrate into a fixed system with other instrumentation including data loggers or displays.

The MiniAir64 vane anemometers provide a 4-20mA output relative to the flow velocity ranges of up to 20m/s or 40m/s. The units are simple to install or use as part of a fixed system or in conjunction with data loggers, displays or portable indicators. The sensors operate from a 9-24vDC power supply. The operating temperatures of the standard MiniAir64 probe is -10 to +80°C. High temperature units can be supplied with external electronics and probe operating temperature ranges up to 140°C.

These MiniAir vane anemometers come with Ex certification and provide linear voltage or current outputs relative to the flow velocity ranges of up to 20m/s or 40m/s. Each unit comes with external electronics and EX barrier, with a standard 20m cable between the probe and electronics. The electronics must be located in a safe area with probes in the hazardous zone. The units are simple to install or use as part of a fixed system or in conjunction with data loggers, displays or portable indicators located in the safe area.

The MC 4.0 Junior is the entry level device in the MC 4.0 range. Like the MC 4.0 anemometer, the MC 4.0 Junior is suitable for determining the flow velocity, temperature and relative humidity of gaseous and liquid media. The measurement with a vane anemometer is considered to be the most accurate of the possible measurement methods. As a further bonus, the periodic calibration of the MC 4.0 Junior only requires the renewal of the measuring heads. This means that the device does not need to be sent in as with comparable products. Vane anemometers are available with plastic sensors that can be used for non-aggressive gases or liquids and Steel sensors suitable for use in aggressive media or higher temperature ranges.
