Air Monitor VELTRON III Key Features

3% of Reading Accuracy when combined with Air Monitor probes versus traditional percentage of full scale.

Dual-Channel capability minimises the need for multiple transmitters. It can be used for a split system by combining or subtracting two flow rates, or a dual system by monitoring two independent flow streams.

Extended Flow Range – using the dual transducer technology, the turndown ratio can be maximized for specific application to ensure optimal performance.

Air Density Compensation – dynamic changes in temperature and barometric pressure can impact readings. Selecting an RTD allows the transmitter to calculate real time air density for ACFM.

Field Characterisation capability to improve the overall performance of the system when installed in non-ideal locations.

Relative Humidity Adjustment – preconfigured RH scenarios selections for return & supply air, or custom conditions can be entered for a more precise actual airflow measurement (ACFM) versus traditional DP transmitters which use dry air conditions to perform air flow rate calculations.

BAS/BMS Interface options include up to four programmable analogue outputs and one RS485 interface for native BACnet or MODBUS protocols. Multiple Enclosure Options to accommodate a variety of installation locations with environmental protection requirements.
