T-8 disc meters are no longer manufactured, so all TRICON/E transmitters manufactured for disc meters are
the T-10 type. In most cases, the newer T-10 meter chamber is smaller than its corresponding T-8 meter
chamber, which results in the TRICON/E having a theoretical "Flow Rate at 20mA Output" that is greater than
the Maximum Flow Rate allowed for the meter. This means that the T-10 type TRICON/E running on a
T-8 meter will never actually reach the 20mA output level during normal operation. The calculated flow rate
required to produce a 20mA output is a reference for calibrating the 4-20mA receiving instrument.
