death or serious injury.

CAUTION Cautions are indicated when mishandling this product might result in

minor injury to the user, or only physical damage to the product.

WARNING

Never allow gases that are within explosive limits to pass through this device. Doing so could

result in an explosion.

Do not use this device for oxygen gas. Doing so could result in a serious accident.

Safety Precautions

CAUTION

Be sure to use this device within the flow rate range stated in the specifications. To prevent

excessive flow, use a suitable means to control the supply pressure or use a throttle valve or

the like to control the flow rate.

If damage could result from the abnormal functioning of this device, include appropriate redun-

dancy in the system design.

If there is a risk of a power surge caused by lightning, use Azbil Corporation's SurgeNon to

prevent possible fire or equipment failure.

When carrying the flowmeter or connecting it to the pipe, do not hold it by the measurement

module. Doing so could cause damage, or the device could drop, causing an injury.

To avoid damaging this device, do not use it outside of the operating pressure range. Also, do

not subject it to a pressure above its pressure resistance.

When maintaining or replacing the measurement module, release the internal pressure of this

device before removing the measurement module.

Chapter 1. OVERVIEW

■Summary

The MCF air flowmeter uses a µF (Micro Flow) sensor in its sensing unit. The µF

sensor is a thermal flow speed sensor which uses proprietary technology.

Integrating this ultra-miniature flow speed sensor with high-grade channel design

technology has achieved high accuracy and wide rangeability.

■Features

•Incorporates a thermal flow speed Micro Flow sensor. With the silicon micro-

machining and the thin-film forming technologies, the µF sensor is a mere 1.7

mm square and 0.5 mm thick, and features high sensitivity and fast response.

•Because this device is a mass flowmeter, its readings are not affected by temper-

ature or pressure.

•The MCF with 4 to 20 mA output provides instantaneous flow rate and inte-

grated flow display, and provides analog current output for instantaneous flow

rate, as well as event outputs for integration pulse or alarms.

The MCF with RS-485 communications provides instantaneous flow rate, inte-

grated flow display and RS-485 communications function.

•A bypass structure using orifices affords a wider flow rate range per pipe size

than previous mass flowmeters, with low pressure loss.

•Dust tightness is improved by the bypass structure and flow path design.

•Self-diagnostic function for easy handling of malfunctions.

•Measurement module is detachable, so maintenance can be done without remov-

ing the flowmeter.

•Measurement module can be swapped between the MCF0250, MCF0400 and

MCF0500.

•Display unit can be rotated, for viewing from the desired direction.
