DPT-Flow transmitters are unique devices that make measuring air flow easier than ever before. Together with FloXact™ measurement probes the same devices are the right option when measuring flow in a duct. Again, if you wish to measure air velocity, your selection would be AVT which offers multiple measuring ranges in a single device together with relay and temperature output signals. DPT-Flow-Batt is an on-site display for air flow or differential pressure designed for environments where electricity is not available.
