    Transmitter provides flow rate indication, totalization DIGITAL INDICATOR-TOTALIZER-TRANSMITTER of flow volume and a current output signal proportional INDEX to the rate of flow when mounted on our meters. The TR28-2 is for installation on propeller meters. I. DESCRIPTION II. SPECIFICATIONS: ACCURACY Rate ±0.25% of reading.
