FLOWMETER
OPTIONAL ACCESSORIES
Signal Conditioners/Converters
CAT Series (Refer to CAT Technical Data Sheets).
Meter Mounted Totalizer/Rate Indicators

To achieve optimum performance of the Sanitary Turbine
Flowmeter, a minimum of 10 pipe diameters upstream and 5 pipe
diameters downstream of meter size pipe must be used.
In addition, certain combinations of nominal meter sizes and triclamp sizes, as indicated on the sizing chart, require the use of
adaptor piping to meet the latest “3A” 28-03 specifications. To
meet these requirements, Hoffer offers optional sanitary
installation kits to provide appropriate straight runs before and
after the meter to produce optional results. Certain sizes
indicated in these kits to meet the latest 3A standards. Contact
factory for additional details.
