SIGNAL CONDITIONERS FOR
TURBINE METERS
Suitable for Direct Mounting onto FTB-930
and FTB-940 Series Flowmeters
FLSC-64
FLSC-61
0 to 5/0 to 10 Vdc Output
The FLSC-61 is a 3-wire analog
transmitter designed to linearly convert
a frequency input to an equivalent
voltage output whose level is switch
selectable @ 0 to 5V/0 to 10V.
A full scale frequency range of
75 Hz to 10 kHz is jumper-selectable.
The span adjustment establishes the
frequency point at which the full scale
voltage output (5 or 10V) is achieved.
A sensitivity adjustment permits the
FLSC-61 to discriminate between a
signal input and noise.

FLSC-62A
4 to 20 mA Output
The FLSC-62A is a 2-wire
loop-powered analog transmitter
designed to linearly convert a
frequency input to an equivalent
4 to 20 mA current output.
A full scale frequency range of
100 Hz to 10 kHz is switch
selectable. The span adjustment
establishes the frequency point at
which a 20 mA output is achieved.
A sensitivity adjustment permits the
FLSC-62A to discriminate between
signal input and noise.

Minimum: 7V + (20 mA x RL)
Maximum: 28V + (4 mA x RL)
Analog Output: 4 mA @ 0 Hz, 20 mA @
desired full scale frequency
Full Scale Range:
100 Hz to 10 kHz, selectable
Response Time:
95% of change in 1 second
Linearity: 0.3% FS
Temperature Coefficient: <2% of rdg
over entire temperature range
Minimum Load Resistance: 250 Ω
Maximum Load Resistance: 500 Ω

FLSC-64
Amplifier Squarewave Output
The FLSC-64 amplifies and conditions
low-amplitude signals such as those
developed by a magnetic pickup coil.
The amplitude of the squarewave
output equals the input supply
voltage of the FLSC-64.
A sensitivity adjustment permits the
FLSC-64 to discriminate between
an input signal and noise.The
FLSC-64 contains a built-in test
oscillator that enables the operator
to verify the amplifier’s operation
without a signal source. The power
LED illuminates when the input
supply voltage is present.
