K-Factor The meter is factory calibrated. The K-factor is found on the label on the meter body and must be input into the control/display for accurate reading.

Positioning Vertical or horizontal installations are acceptable. Straight pipe of at least five pipe diameters is recommended.

FLOW 5 x diameter
Warnings • Do not test with compressed air—doing so will subject meter to rotational speeds many times those for which it was designed and will certainly damage the rotor, shaft, and/or bearings. • When connecting to pipe, do not over tighten, especially when connecting to metal pipe. • At least five pipe diameters of straight pipe is recommended upstream from the meter.

Connections Connecting to Seametrics Control Devices When connecting the SES to a Seametrics control device, refer to instructions that come with that device.
Connecting to Non-Seametrics Control Devices The SES is well suited for connecting to PLCs or industrial computer boards. They can typically be connected directly or with a single resistor. Requirements are as follows: •
PLC sensor power supply must be 5–24 Vdc (24 Vdc is typical)
•
PLC sensor power supply must be able to provide at least 2 mA (100 mA is typical)
•
The PLC frequency response is greater than the flow meter output response. If PLC accepts input from current sinking devices (NPN) Figure 1 Input Designed for Current Sinking (NPN) Devices Red White Black
