acceptable time period. The system should be stabilized in time to prevent premature wear, clogging or damage to meter component s. Installation Contamination Sources Basic Application Information The FreeFlow flow meter can be inst alled directly in the fluid line without flow straighteners or special piping. The meter’s primary use is for water measurement applications. Fresh Fluid When fresh fluid is stored in holding t anks, it may be contaminated with scale or particulate from inside the tank.
) Operating Temperature: In standard meters, several components have a maximum temperature rating of 170ºF (76ºC). 5) Operating Pressure: Meters should not be used over 10% of the operating pressure rating. 6) Pipe Sealer: Care should be taken when choosing a pipe sealing method. The use of pipe sealing pastes is often discouraged when sealing plastic fittings. Basic Installation Instructions The meters are mounted in-line and provide an electrical output that is proportional to flow rate.
4-20 mA Configurations Configuration / Operating Modes Device Settings: (Refer to Table 1 for details of this output option.) 1) Using a small flat blade screwdriver, set the 10-position selector switch to position 0. Field Configurable Outputs The FreeFlow meter can be field configured to of fer a variety of output protocol signals. Possible outputs protocol options are 4-20mA, 0-5Vdc and 0-10Vdc. The following steps must be taken prior to making any field configuration changes.
0-5 Vdc Configurations 0-10 Vdc Configurations Device Settings: (Refer to Table 1 for details of this output option.) 1) Using a small flat blade screwdriver, set the 10-position selector switch to position 1. Device Settings: (Refer to Table 2 for details of this output option.) 1) Using a small flat blade screwdriver, set the 10-position selector switch to position 2. 2) Verify that the 2-position jumper JP1 is shunting pins 2 & 3. 2) Verify that the 2-position jumper JP1 is shunting pins 2 & 3.
