Instruction Manual
Direction of Flow
TS Series flow meters can operate in either direction.
Standard assembly, when facing the flow meter, has the
flow going Left-to-Right, unless specified differently at time
of the order. A label with the word INLET is placed on the
inlet flange, as assembled at the factory. To change the
direction of flow:
1. Reverse the position of any accessories attached to the
flow meter.
2. If Quadrature pulse signal is used, reverse output leads
for channels A & B on the TBB (or SCL):
TBB SCL
L-to-R R-to-L
WHITE: On A On B
GREEN: On B On A
NOTE: The ELNC register is not W&M certified in
the EU.
The SCL is not yet approved for use in
the EU.

Flow Meter Communications & Direction of Flow
TS Series meters in F●● & W●● assembly have an internal
pulser. The pulse signal generated by the flow meter, can
be fed directly to most electronic registers. In such assem-
blies, flow meter calibration (or re-calibration) is through
correction of the K Factor (number of pulses/unit volume) in
the electronic register.
In some cases an SCL board (#13) is added to the flow me-
ter assembly. This signal conditioner is added when:
1. Flow meter pulse frequency exceeds the electronic
register capacity at maximum flow rate. This can occur
at surprisingly low flow rates (see below).
2.
The electronic register requires a scaled pulse value
(1, 10, 100 or 1000 pulses/volume unit).
3.
Local authorities demand a mechanical calibration de-
vice. The SCL includes two dials with setting from 00
to 99. Changing the setting by 1, represents approx.
0.03% correction to the pulse signal.
NOTE: K Factors shown here are nominal (average).
Individual flow meters can vary slightly; and all flow
meters will shift to some degree with viscosity fluctu-
ations (see page 1.14)
