Seametrics S Series Instructions

General Information
These versatile impeller flowmeters in 3/8" to 1"
nominal pipe size employ jewel bearings for very low
minimum flows. The 6-24 VDC pulse output of these
meters is compatible with many different types of
control, including a full range of SeaMetrics rate displays
and controls. The SeaMetrics FT420 provides flow rate
and total flow, with 4-20 mA ouput. For metering pump
pacing or interfacing with lowspeed counters, the PD10
divider is recommended. The AO55 is a blind 4-20mA
transmitter.
S-Series meters are available in 3/8" to 1" nominal sizes.
The SPX body material is polypropylene, with transpar-
ent a c r y l i c c o v e r s f o r v i s u a l f l o w i n d i c a t i o n .
Polypropylene covers are available as an option.
The SPT is available standard with TFE housing, TFE
cover, PVDF rotor, ceramic shaft, choice of o-ring
material (EPDM or Viton), and optional silicon carbide
shaft.
