Chapter 7. SPECIFICATIONS
*9: If no flow or reverse flow continues for 15 seconds or more, the MCF will go into standby mode to reduce power
consumption, and the measurement cycle will be automatically switched from the usual 1 s to 10 s. When a nor-
mal (forward) flow is detected again, the cycle returns to 1 s.<0} For details, refer to ”Standby mode” on page
20.
*10: If the MCF is in standby mode 12 hours a day, the battery life is about 3 years. (The battery replacement alarm
will be activated in about 2.5 years.)
If it is in normal mode (continuous measurement) 24 hours a day, battery life is about 2 years. (The battery
replacement alarm will be activated in about 1.6 years.) These reference values are for new batteries whose
capacity is eqaul to that of the included batteries, when they are used at normal temperature.
