WFC/5 FREQUENCY TO CURRENT CONVERTER
converts the pulsed output from your flowmeter into an analogue 4-20mA or 0-10V
Quick and easy to install
Monitor consumption and flow rates
Improve your process
Reduce costs and waste
Immunity to electrical noise
The WFC/5 will convert a pulsed flowmeter signal into an
analogue signal for instruments such as PLCs, computers, flow
controllers, chart recorders, indicators or moving coil
weatherproof, insulated, impact and chemically resistant enclosure allows the
instrument to be installed almost anywhere. It can be mounted in a panel or on
to a wall via integral holes in the case.
The WFC/5 will accept any pulsed signal from a flowmeter.
It provides you with two analogue outputs of 4 - 20 mA and 0 - 1 mA.
unscaled (one to one) 5 V TTL pulse can also be used for instruments requiring
a square wave pulsed input.
The instrument has a DC power supply for
Overrun compensation: The controller can
automatically compensate for errors caused by slow acting valves and deliver
exactly the volume you want.
No flow alarm: If there is a problem
and the signal from the flowmeter stops an alarm will be given and the batch
will be stopped.
Linearisation: The accuracy of your system can be
improved by programming any flowmeter errors into the BC7.
There is a non
resettable total to allow you to monitor long term usage.
The Batch Controller is in a standard 1/4 DIN format to
mount in a panel.
The front keypad is a sealed unit which provides you with
a splash proof seal that is resistant to most chemicals.
