Cameron’s NUFLO MC-I Portable Rate Meter is a portable liquid and gas measurement device that provides a continuous display of flow rate and total volume. Packaged in a compact carrying case with a handle, the instrument is easily transported from one field location to another for verifying turbine meter operation. The MC-I Portable Rate Meter is accurate, easy to use, and compatible with NUFLO turbine flow meters of all sizes. An LCD screen simultaneously displays volume and flow rate in a variety of commonly used engineering units. Volume is displayed on the top line of the readout and the operator selects the decimal point position during calibration. Flow rate is displayed on the bottom line of the readout, and the decimal point position is automatically set in accordance with flow rate to provide maximum resolution as flow rates change. The MC-I Portable Rate Meter is easily configured for liquid or gas measurement using the five-button keypad. For liquid, a user enters the calibration factor of the flow meter and selects the desired units for volume and flow rate. For gas, a user enters a manually calculated divisor and selects a desired time base for rate.
