*1 Connecting a carbon steel pipe for pressure service (JIS G 3454) or a stainless pipe (JIS G 3459) greater than schedule 40 will cause decreased accuracy. (The larger the schedule number, the smaller the inner pipe diameter. For this reason accuracy is affected.)

Do not connect a smaller size pipe to theMCFwithout a section of straight pipe. Even though there is a regu-lar forward f low in themain f low path, theremay be a reverse f low in themeasurementmodule, resulting in adisplay of “–0.”Alternatively, the displaymay show a f low rate that is considerably lower than the actual rate.If theMCF is connected to a pipemore than one size smaller (e.g.,MCF0150 to a¼Bpipe), add 5D to the speci-fied straight pipe length* before theMCF.

Handling Precautions• If the device is mounted on a horizontal pipe with the display facing right or left when viewing the air inlet, setting the

low-flow cutoff to "5" (±5 % of FS flow rate) or less is recommended. If the low-flow cutoff is not set, a flow rate may be displayed when there is no flow, and the amount of total flow may be increased by the totalizing/reverse-totalizing function.

• Mounting on a horizontal pipe with the display unit facing downward (orientation #4), mounting on a vertical pipe (orientation #5)Thecharacteristicsofthedevicedonotchangeascomparedwiththestandardposition.However,ifthedeviceismountedonahorizontalpipewiththedisplayfacingdownward,accuracymaydecreaseovertimeduetotheaccumulationwithinthesensorofmoisture,mist,ordustfromthemeasuredfluid.
