Flow meters,
Flow switches and
Flow transmitters
For Circulating Lubrication Oil
LL Series, with standard scale
and pointer (control box A).
DESCRIPTION
These variable-area meters
position an orice over a tapered
shaft to establish ow rate.
Mounting is in-line and in any position. Straight pipe runs before or
after this monitor are not required.
The all-mechanical sensing
system directly drives the pointer,
switches and transmitters.
Readout is visual with a pointer
and scale combined with either
switches or a 4-20 mA transmitter.
LINE CONNECTION
The ports are threaded, can be
NPT or SAE straight-threads from
1/8 to 3/4 inch. Metric threads such
as BSPP or BSPT are also
available.
INSTALLATION
Flow monitors mount offset and are
typically supported by rigid pipe.
SPECIAL OPTIONS
CALIBRATION
All ow meters are individually calibrated for uids with the
viscosity you specify (up to 1475
SSU/300 Centistokes). We also
compensate for your uid’s specic gravity. For NIST Traceability
please consult factory.
Identication tag: (option ST) customer-supplied information is stamped
on a stainless steel tag that is attached
to the nameplate.
High Vibration: (option ZRL)
Unit is modied for high vibrations with
added roll pins and screw adhesives.
ENGINEERING DATA
CONSTRUCTION MATERIALS
Construction is Aluminum/Polysulfone meter body, Stainless
steel and Brass internal moving
parts with Buna-N seals.
Maximum uid temperature: 200°F
(93°C)
Maximum ambient temp: 150°F
(65°C)
Series LL max. operating pressures:
150 PSI (10.34 BAR)
Pressure drop: 5 PSI (.35 BAR) at
full scale
Readout accuracy, full scale: ±5%
Switch repeatability is 1% of actual
ow
Fluid ow causes a springloaded piston A having a
circular opening at its center B to move along the axis
of a precision-tapered shaft
C. This creates a variable
orice in direct proportion to
the ow rate. The piston is
mechanically linked to the
readout pointer D and actuates switch E or a transmitter (not shown).
