VOLU-flo OAM: Outside Air Monitor

This patented World Class design simply and easily measures outside air flow from inlets, it is unaffected by dirt and moisture because of its unique design and is offered in stations that include the expanded metal, OAM, Inlet Reference Sensor, and Inlet Temperature Sensing RTD.  The OAM is revolutionizing how air flow is measured and is the first option to measure air flow in both new buildings and retrofits.


Is ideally suited for both new installations and retrofit applications where the airflow is in location offering limited amount of straight run. Operating on the Fechheimer principle to measure the total and static pressure components of airflow, the location of the ports and the sizing of the tube provide extreme performance in normally difficult to measure areas. Options to mount externally, or internally, insertable/removable, or self-supported, there is truly a VOLU-probe for all applications.

Veltron DPT2500 Plus:

This smart transmitter is furnished with an automatic zeroing circuit, for applications operating in a moderately steady temperature location, this automatic zeroing basically functions as a “self-calibrating” transmitter. This extremely accurate transmitter can hold 0.1% of Natural Span, add in the three line LCD display and you have the best Airflow DP transmitter in the world.

Thermal Dispersion:

Utilizing two matched thermistors, one is heated and then the airflow is calculated based on the heat transfer and the defined relationship between heat transfer and airflow velocity. Each sensor measures airflow within 2% of actual point velocity and temperature within +/- 0.1F.


Integral Transmitters make installation a breeze allowing the wires to be run directly back into a BAS system.

ELECTRA-flo Probe Transmitter:

Offering up to 16 sensors per probe for the densest probe array and best in world accuracy. Transmitter allowing for probes to be daisy chained together with a single home-run back and 32 sensors per probe array or measuring station. ELECTRA-flow stations are available to minimize the set-up for either new construction or retrofits applications.
