The VELTRON DPT-plus transmitter is furnished with an automatic zeroing circuit capable of electronically adjusting the transmitter zero at predetermined time intervals while simultaneously holding the transmitter output signal. The automatic zeroing circuit eliminates all output signal drift due to thermal, electronic or mechanical effects, as well as the need for initial or periodic transmitter zeroing.
The MASS-tron II Multi-variable Mass Flow Transmitter is a VELTRON II Transmitter with the addition of both process temperature and pressure compensation. This ultra high accuracy transmitter includes analog outputs for process differential pressure, temperature and absolute pressure, an analog input for process temperature and a temperature compensation selection feature.
The VELTRON II Transmitter is an ultra-low differential pressure and flow "smart" transmitter. With its ±0.1% of natural span accuracy, it is intended for the most critical and demanding HVAC and industrial applications requiring the utmost accuracy and long-term stability.
Air Monitor CAMS™ – COMBUSTION AIRFLOW MANAGEMENT SYSTEM
The CAMSTM – Combustion Airflow Management System contains the microprocessor based instrumentation to measure the airflow and manage the AUTO-purge in combustion airflow applications.

ir Monitor's AUTO-purge III is designed for applications where the continuous exposure to airborne particulate might impair the measurement accuracy of our Combustion Air Station (CA Station) or our VOLU-probe/SS array. When activated by one of our "smart" flow transmitters or a distributed control system, a combination of valves are operated to introduce high pressure, high volume air into the flow measurement device's sensing ports for a short duration while simultaneously isolating the transmitter from over-pressurization. This periodic purging assists in maintaining the sensing ports of the total and static pressure manifolds in a clear unobstructed condition.
Air Monitor ACCU-FLO HIGH ACCURACY STAINLESS STEEL STATION
The ACCU-flo/NP is a combination precision nozzle and multi-point, self-averaging Pitot airflow measurement station. When combined with an ultra high accuracy transmitter, such as Air Monitor’s VELTRON II< MASS-tron II or VELTRON DPT-plus, the ACCU-flo/NP provides high accuracy (±0.5%) flow measurement for process monitoring and control applications. The combined effect of the integral flow straightener cell and the nozzle means little or no upstream straight run is needed to achieve the published accuracy.
Air Monitor CA STATION – COMBUSTION AIRFLOW MEASUREMENT STATION
The CA Station measures the total and static pressure components of airflow. The combination and dispersion of total and static pressure sensing ports minimizes the effect of directional airflow, and the addition of the honeycomb airflow processing cell makes the CA Station extremely effective at accurately measuring airflow in limited straight duct runs.
Air Monitor LO-FLO/SS STAINLESS STEEL PITOT TRAVERSE PROBE
The LO-FLO/SS is all-stainless steel combination air equalizer/straightener with self-averaging Pitot tube traverse station provides highly accurate measurement of low air volumes ranging from 2-2000 CFM. It is capable of operating up to 1000°F in a variety of applications, including applications with corrosive gases, within the limitations of the 326 stainless steel construction.
Air Monitor VOLU-PROBE SS – STAINLESS STEEL TRAVERSE PROBE
The VOLU-probe/SS Stainless Steel Airflow Traverse Probe is ideal for clean or harsh and particulate laden applications operating at temperatures ranging from -20 - 900°F. It consists of multiple Pitot total and static pressure sensing ports positioned along the length of each probe to traverse the duct cross-section. They average the sensed pressures in their separate internal manifolds and provide velocity pressure measurement accurate to within 2-3% of actual flow.
The VOLU-probe/SM Airflow Traverse Probe is ideally suited for installations requiring accurate flow measurement in pipes or small duct locations with limited straight runs. The “tube-in-tube” design has multiple total and static pressure sensing ports along the length of the probe to traverse the airstream in a single line across the duct or pipe. This provides separately averaged pressures at the signal connections. The VOLU-probe/SM is suited for clean applications operating at temperatures ranging from -20 – 900°F. Applications include fiber quenching, process drying, emissions monitoring, wastewater treatment, and more.
