He MC-II Flow Analyzer provides separate, continuous digital displays of flow rate and accumulated flow based on input from a turbine flowmeter. The low current consumption of its liquid crystal displays and CMOS microprocessor based circuitry enable years of dependable performance from a single lithium battery. Typical battery life is 3 to 5 years. Totalizer readings can be made in any desired volumetric units, and flow rates can be measured in units per second, minute, hour, or day. Rate Katup Valve
