Air Monitor Corp 13200AZ Flow Transmitter Controller

Air Monitor Corp 13200AZ Flow Transmitter Controller is a differential-pressure‑based flow transmitter in the VEL‑Trol/VELTRON II family, designed for accurate airflow measurement and control in commercial HVAC and industrial systems. The transmitter, built around Air Monitor’s ELECTRA‑flo Plus platform, is intended to be used with a probe array or station and features an integral multi‑line digital display for configuration and normal operation. It supports remote mounting via an interconnect cable up to 100 feet away from the sensing station, enabling flexible installation in tight spaces. Typical spans run from 0 to 25 inches water column, with an accuracy specification of about ±2–3% of actual flow, depending on installation and span, and it can be configured for various flow calculations using the VELTRON/MASS‑tron family firmware. Optional purge capability allows automatic high‑pressure purge cycles of the airflow station when needed, while maintaining the transmitter output during purge cycles. The VEL‑trol II and VELTRON II platforms are manufactured at Air Monitor’s Santa Rosa, California facility, underscoring a long‑standing heritage in precision airflow measurement.
