WS/5
FLOWMETER SCALER 
The WS/5
converts an unscaled flowmeter pulse into two scaled pulse outputs and an
analogue output of 0-1mA or 0-5mA
Quick and easy to set up
Preset to
your requirements
Works with all pulsed flowmeters
Outputs for
PLC’s,computers etc.
Highly accurate
Monitor consumption and flow
rates
High reliability
Immunity to electrical noise
Weatherproof
enclosure
Application
The WS/5 will convert any unscaled pulsed signal from
your flowmeter into two scaled pulse outputs suitable for connection to
totalisers, PLC’s, control systems and computers. The two isolated outputs
can be used for separate systems for example a local display and a computer
input. The analogue output can be used as an economical means of displaying the
flow rate on a separate indicator.
Installation
The
weatherproof, insulated, impact and chemical resistant enclosure allows the
instrument to be installed almost anywhere via integral holes in the case.
Instrument Function
The WS/5 will accept any pulsed signal from a flowmeter
and convert it to two scaled pulse outputs and one analogue 0-1mA or 0-5mA
signal. The duration of the pulse output can be adjusted to suit your
rquirements. The WS5 can be supplied with an integral display, either an
analogue dial for flowrate indication or an LCD totaliser. The instrument has a
DC power supply for sensors.
