Page 6: General Information
The packing list is inside the red information packet along with the Installation and Operation Manuals. The POD mounts directly to the front cover of any Liquid Controls meter in place of the packing gland. The motion of the meter’s blocking rotor is magnetically coupled through a stainless steel wall to the electronics compartment of the POD. - Page 7 Pulse Output Device · POD2 – Fork Drive with PTFE O-Ring, 100 PPR Quad Pulser, 9 to 30VDC · POD3 – Blade Drive with Buna-N O-Ring, 100 PPR Quad Pulser, 9 to 30VDC · POD4 – Blade Drive with PTFE O-Ring, 100 PPR Quad Pulser, 9 to 30VDC ·...
- Page 8 When initially calibrating a specific meter model, the K-Factor (Pulses/Unit) values given below are for reference only and are not to be used as a final K-Factor. NOTE: ll Liquid Controls meter models listed below assume use of the 400ppr pulser with a 1:1 Packing Gland/Face Gear ratio when calculating the Pulses/Unit.

Page 15: Installation
Pulse Output Device Installation POD Installation New Installations When ordered with the flowmeter, the POD comes factory installed on the meter and ready for wiring. Wiring instructions begins on page 10. RELIEVING INTERNAL PRESSURE All internal pressure must be relieved to zero pressure before disassembly or inspection of the strainer, vapor eliminator, any valves in the system, the packing gland, and the front or rear covers. - Page 16 Pulse Output Device Retrofit Installations Follow these procedures to remove the existing hardware: 1. Relieve the pressure from the process piping to the meter. 2. Drain the meter by opening the meter’s drain plugs. NOTE 1: Meters with only two packing gland mounting screws are limited to four orientations.
- Page 17 Pulse Output Device Installing the POD POD Extension Kits If a POD Extension Kit is necessary, it must be installed prior to installation of the POD. See POD Extension Kit Installation Follow these steps to install the POD onto a flowmeter: 1.

The POD Extension is used to extend the connection away from the meter. There are four POD Extension models available: · 49754 POD1 or POD5 – Fork Drive with Buna-N O- Ring · 49756 POD2 – Fork Drive with Teflon O-Ring ·... -
Page 19: Pod Wiring
Pulse Output Device Follow these steps to install the POD Extension: 1. Verify that the proper POD Extension Model was obtained by comparing the driver tang on the POD Extension to the driver tang on the packing gland that was removed in Step 5 of the Retrofit Installations section of the Installation topic... - Page 20 Pulse Output Device must be engaged five (5) full threads into the female hub on the POD to meet explosion proof requirements. When installing in a Division 2 location, use either rigid conduit, flexible conduit, or no conduit. When no conduit is used, the instrument cable must be brought into the POD conduit hub using a cable gland to seal the wiring to maintain the Enclosure NEMA 4X rating.
- Page 21 Pulse Output Device Before inserting wires into the terminal block, strip ¼" of insulation off each wire. Turn each terminal screw counterclockwise a few turns to make sure that the wiring slot is fully open to accept wire. Insert the stripped end of the wire and tighten the terminal block screw. Plug the terminal block back into the board if it was removed.
