Process Panel Display Model MPV
Description
The MPV is designed for simultaneous display of both the flow
rate and total for flowmeters with analog or pulse outputs. The
upper display can be programmed to display flow rate, total,
or grand total and the lower display can be programmed to
display flow rate, total, grand total, engineering units, custom
legends, or can be turned off. Both displays are also capable of
displaying relay set points, or maximum and minimum values.
They are also able to provide power to the flowmeter. The MPV
features a rugged design with a unique front panel that is nearly
impenetrable in typical applications. Set-up is easy with the
user-friendly dual line display.
