The VELTRON III Transmitter is a dual range pressure and flow transmitter. The dual-transmitter technology allows for an expanded span of measurement with precision accuracy of 3% of the reading. Utilizing temperature sensors to perform air density corrections, it enables Actual CFM (ACFM) to be provided. The transmitter has independent dual-channel readings to reduce the need for multiple transmitters and it comes with BACnet or MODBUS communications.
