RT40 Flow Rate Totalizer
RT40 Flow Rate Totalizer
FLOMEC® LCD display RT40 is specifically designed for displaying flow rates and totals from flowmeters with pulse, sine wave or frequency outputs. A robust aluminum housing and acrylic front cover make it suitable for heavy duty use in mine sites and mobile applications. The instrument displays re-settable (batch) total, cumulative total and instantaneous flow rate in engineering units programmable by the user.
