Installation and Instruction Manual MODEL COIN Flow Meters
PRESO COIN LOCATION INSTRUCTIONS Straight pipe requirements: Accuracy is affected by the piping configurations due to the disturbances of the flow profile. A fully developed symmetrical flow profile is achieved with the minimum upstream and downstream recommended lengths. NOTES: 1 - For upstream and downstream lengths equal to one half the values shown add 1 percent to the accuracy value.
STRAIGHT PIPE RUN REQUIREMENTS As with most flow elements, proper operation and performance is dependent on the required lengths of unrestricted upstream and downstream piping. The recommended minimum length of the upstream side of the COIN Flow Element depends on the type of fitting at the start of the straight run, and the pipe configuration. Minimum upstream and downstream lengths are shown in the location instructions on back page. The minimum lengths will cause a slight coefficient shift.

WARNING: Never exceed the maximum pressure or temperature recommended for the measured process. Exceeding proper pressure or temperature ratings can lead to personal injury or equipment damage. The process piping flanges should be identical to those on the COIN meter. The process temperature and pressure should never exceed that for which the element was designed. LINE INSTALLATION All flanged COIN flow elements require a gasket between the process line connection and the mating flange.
When installing chemical tee seals tighten cap screws uniformly in a “star” pattern to avoid localized stresses on the gaskets. The ANSI flanged taps seals require a backup flange rated for the same type and class as that on the COIN element. Backup flanges with bolts and nuts are generally offered as an option to the transmitter and are not supplied with the COIN element. Again, observe recommended torque specifications for the type and class being used.
