T-8 disc meters are no longer manufactured. Therefore, all TRICON/E transmitters manufactured for disc meters are the T-10 type. In most cases, the newer
2
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 provided as a reference for use in calibrating the 4-20mA
receiving instrument.
