Air velocity and flow measurement for air handling and ventilation

The Model AAFS air flow switch provides excellent sensitivity and reliability at a very reasonable price. Quality features include a rugged die cast body, stainless steel vane and SPDT snap switch. Unit is field adjustable from 400-1600 FPM. Mounting is fast and simple,with only two screws needed. Vane fits 6 inch or larger ducts.

The reliable IVL air velocity transmitters work on the hot-wire measurement principle, which quarantees very good accuracy at low air velocity. The transmitters are suitable for air flow and temperature measurements in the air ducts. Air velocity transmitters are available with different measurement ranges and immersion lengths, with or without display.

Micaflex MF-FD is a flow linear differential pressure transmitter specially developed for measuring air flow, together with all types of flow sensors with known flow constant, e.g. MFS flow sensor in ventilation ducts, chambers and rooms. They have an adjustable damping and a choice between a 0-10 V or 4-20 mA output. The flow transmitter is fitted with a 4-digit LED display for indicaiton of c...

The MF-PFA series can measure the airflow in combination with the self-averaging MFS flow sensors in addition to differential pressure. Besides analog outputs, this series also features a built-in PI controller, which can directly controll a fan and 2 swithes for local alarms. Due to the high accuracy and stability, the MF-PFA is ideal for use in laboratories, hospitals and clean rooms. Each in...

The MF-PFT series can measure the airflow in combination with the self-averaging MFS flow sensors in addition to differential pressure. Besides analog outputs, this series also features a built-in PI controller, which can directly controll a fan. Due to the high accuracy and stability, the MF-PFT is ideal for use in laboratories, hospitals and clean rooms. Each instrument is fully programmable.

The Series PAFS-1000 Lightweight Flow Sensor is ideal for sensing differential pressure in the inlet section of variable air volume terminal units and fan terminal units. Units can also be used to sense differential pressure at other locations in the main or branch duct systems.

The Kimo CTV110 is a series of air velocity transmitters with or without display. The CTV110 is ideal to use as flow measurement in air ducts, fume hoods and laminar flow cabinets for connection to a building management system. The installation is very easy and the housing can be mounted in two parts making it ideal for installers.

The Kimo CTV210 is a series of air velocity transmitters with or without display. The CTV210 is ideal to use as flow measurement in air ducts, fume hoods and laminar flow cabinets for connection to a building management system. The transmitter can be carried out with a standard stainless steel probe, or a special omni-directional probe.

The Dwyer AVUL series measures air speed and volume flow in ventilation ducts. The AVUL works on a hot wire principle with special coating for a long life. There may be chosen for English or metric units. Furthermore, there are analogue outputs, but also versions for Smart Buildings with BACnet or Modbus communication.

The Debimo self-averaging flow sensors work on the same principle as a pitot tube. The advantage of this measurement principle is that non-laminar air flow can still be measured reliably. The Debimo sensors are made of aluminum and are available in a wide range of standard lengths. In addition, the sensors can also be customized.

The MiniAir64 vane anemometer measures the speed of gaseous media and water, with a direct 4-20mA output. The Swiss Precision MiniAir64 Vane probe is unique. The lamella rotation has a very low resistance and is not affected by pressure, temperature, density and humidity. The MiniAir64 is also available with an ATEX certificate.
