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...

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 MFS flowsensor is a patented, self-averaging flow-sensor for all kinds of ventilation ducts. The average of air flow is measured across the whole length of the sensor. Gives a 2,5 times higher differential pressure than a Prandtl tube measuring. Easy to install in existing ducts. Lengths from 100 to 2500 mm.
Micatrone's flow sensor MFS-SS has been developed to meet the great demand for accurate air flow measurement in all types of air-handling systems. The MFS-SS is based on the principle of averaging the velocity profile over the height or the diameter of the duct.
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.
KIMO offers a wide range of high-quality and accurate Pitot tubes, as per the AFNOR NFX 10-112 norm. These Pitot tubes, when being connected to a differential column / or needle / or electronical manometer, can measure the dynamic pressure of a moving fluid in a duct, and then can deduct its air velocity in m/s and its airflow in m3/h. These Pitot tubes are used in HVAC field, vacuum cleaning a...
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 new C310 series are multifonctional transmitters which can be extended by an internal pressure module and two external probes. The display can show up to 4 parameters, but can also display a trend graph and the min/max values of each channel. The C310 has two analog outputs, which can be extended by two more. Modbus and Ethernet communication are available as an option.
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 Dwyer DH3 series Digihelic differential pressure gauge is a 3-in-1 instrument with a digital display, relay contacts and a transmitter output, all packed in the popular Photohelic housing. By combining these 3 functions, you can reduce different instruments to one product, saving you inventory, installation time and money. The DH3 controller is the ideal instrument for pressure (difference)...
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 ATEX certified AT2DH3 series Digihelic® differential pressure controller is a 3-in-1 instrument that consists of a digital differential pressure gauge, relay contacts for alarms, or on-off control and a transmitter output. The AT2DH3 can also be used to measure air velocities and flow in combination with a pitot tube. The AT2DH3 has an analogue 4-20 mA output and two SPDT relay contacts wit...
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.
The Dwyer AVLV series is an air velocity transmitter for very low velocities below 2 m/s. The AVLV has universal inputs for monitoring equipment and the output range can be configured by local DIP switches. Process values can be monitored locally through the optional integral display or the portable remote display tool. The air velocity transmitter is suitable for quality intensive environments...
