In the Operating Condition column Continuous means continuous operation; Intermittent means no more than 8 hours operation a day, and indicates allowable instantaneous flow rate.. Flow range should be selected within the Continuous or Intermittent range specified. 3. For applications where viscosity exceeds 00mPa. s (size 57: 0mPa. s), specially machined rotors are used.. For high viscosity liquid more than 00Pa. s, the meter is not applicable, ULTRA OVAL series are recommended instead. 5. Regarding liquid ammonia, consult factory.
