(ratings shown)

1.2 Transportation Considerations

(1) It is desirable that the monitor be transported to the installation site in the shipping container used for

transit from the factory.

(2) During transportation, exercise care to avoid impact shock and rainwater.

1.3 Storage Considerations

Storing your mass flow monitor for long periods of time upon receipt before installation can result in
un exp ecte d and undes irab le conditions . Whe n long -term storage is anti cipa ted, take th e following
precautions:

(1) The monitor can best be stored in the shipping container used for transit from the factory.

(2) Select the storage place that meets the following requirements:

★ free from rain and water

★ free from vibration and impact shocks

★ with least temperature and humidity variation (around 25°C and 65% R.H).

(3) A monitor that has once been placed in service for any length of time should be washed clean to remove

residue of metered material completely from its main body, joint, conduit, and outer case before storage.
Especially, purge the inner wall of flow path with clean air or nitrogen gas, and then protect the flow inlet
and flow outlet against entry of dust inside.

CAUTION:

1. At cleansing, do not use solvents, such as thinner and alcohol.

2. Never attempt to cleanse the interior flow path with detergent.

S-193-11-E

2. OPERATING CONDITIONS

The monitor operating conditions are stated on the specification label, Section 5 "INSTALLATION" and Section
9 "GENERAL SPECIFICATIONS." Read carefully before initiating operation.

CAUTION:

This monitor is of non-explosionproof configuration; it is not serviceable in a
hazardous location.

3. GENERAL

This monitor is a small, lightweight flowmeter, using a
heat-sensitive resistance element.

Of the two heat-sensitive resistance elements located
perpendicular to the fluid flow; one detects the fluid
temperature and the other, which plays the rol e of
a heater, regulates the temperature of the former to
maintain a constant temperature differential. As the
flow ing process f l uid (ma s s f low) d i s sipate s h e at
from the latter which ser ves as a heater, its supply
power increases in order to maintain the temperature
differential. This change in power consumption (voltage
and current) is used to calculate the mass flowrate.

How to Change Display Orientation

If power is supplied, shut it off. (Make sure

nothing appears on the LCD).

Take off four set screws (3×14) securing the

upper case to the transmitter and carefully
open the upper case (Fig. 5.2).
If a 180 deg. turn is your option, turn the upper
case the other way with lead wires intact (Fig.

5.3).
To turn 90 deg. clockwise or counterclockwise
follow the steps given below.

Take off four set screws (2.6×8) holding the

display board in place and remove the display
board (Fig. 5.5).

5.4 Conditions Required for Metered Fluid

Due to the fact that this monitor is a thermal flowmeter, contamination buildup can cause loss of accuracy. In
an environment where entrapment of contaminants, such as dust, oil, and water, is anticipated, it is a good
practice to provide a filter, drain, separator or similar arrangement upstream of the monitor.

5.5 Tubing Guidelines

(1) Required Tubing Conditions
Since the monitor has a built-in straightener,

tubing conditions, such as differences in tube
diameter, for example, rarely present a problem.
However, if an elbow is to be located upstream
of the monitor, provide a straight tube about the
length of a nipple (3D min.). Direct installation of
an elbow may possibly cause an error of ±1 %
F.S. or so.

There is no restriction on tubing arrangements

downstream of the monitor.

(2) Installation of mounting hardware (option for

meter sizes 15mm and 20mm).

Required tool: Torque screwdriver that fits M3

cross recess pan head screws.

Do not use any other accessories except for the

furnished dedicated screws (tap-tight screws
3 x 8). See outline dimensions in Sec. 12 for
Installation location and orientation.

CAUTION:

With metal tubes, tubing stresses could damage the flowmeter at its metal
fittings. Do not use the mounting hardware with metal tubes. Instead, secure

the metal tubes with U-bolts or similar fittings.

(3) Tube Connection Procedure (for meter sizes 15mm and 20mm)

1. Connecting parts are of aluminum die casting: avoid forcibly installing them and giving an impact

shock. The monitor body is of synthetic resin: avoid applying stresses on it. Torque specification: 30 ±
1 (N・m)

NOTE: Hold the hexagonal flats of aluminum die cast connection firmly with wrench, or similar tool, when

you work (Fig. 5.9).

2. Use care to safeguard the transmitter from coming in contact with tools, such as wrench.

3. Do not hold the transmitter by force while connecting it to the tubing system.

4. Providing a union before and after the flowmeter is suggested to facilitate flowmeter removal.

WARNING

Negligence of the precautions above may result in damaged components.

(4) Flushing
If foreign solids are expected to get into the tubing system, particularly on a new installation, flushing of

the tubing assembly thoroughly is essential before installing the monitor.

(1) When output is given though the flow is stopped (※).
Set the cutoff value a little greater than the output value at that time.
(2) When you want to measure the flowrate of the area lower than the cutoff value, set the

cutoff value lower than the desired flowrate.

Under some condition, the difference at this area may be greater depending on the offset

value of the zero point. Therefore, adjust zero point while the flow is stopped (※) as
necessary.

※ The stoppage of flow refers to the status where the valve at the lower stream of this unit is

fully opened under the process condition in use and there is no leakage from the valve.

8.5 Alarm Features

In this monitor, settings of alarms 1 and 2 are adjustable to any levels to help you keep on monitoring the
process flow. And by setting up two parameters - "lower limit in alarm immunity range" and "alarm immunity
time," precise alarm settings can be established against leaks. Follow the instructions given in this manual
when you set up alarm set points. Examples of alarm setup are also given in this section.

CAUTION:

(1) Setting up the high alarm

Parameters related to the high alarm come in the following five, (1) through (5). Set each of them by

referring to the description given for individual parameters.

① Alarm setpoint

Set the flowrate [(L/min (normal)) to be at the upper alarm.

② Alarm hysteresis

If alarm features are not desired, set the alarm set points to "0" (alarm status
either at high alarm or lower alarm).

Alarm is cancelled when the following conditions are met. Select the appropriate alarm hysteresis [L/

min (normal)].

Flowrate < Alarm setpoint - Alarm hysteresis

If variation in flowrate is excessive, resulting in frequent alarm ON-OFF cycling, set a little larger value.

③ Alarm status (higher digit)

Setting is to be made on the high alarm: set "H" to the higher digit.

④ Alarm status (lower digit)

Set up the output status to the lower digit in an alarmed condition.

Selecting "S" results in an "ON" output (Lo impedance) in an alarmed condition.

Setting "o" results in an "OFF" (Hi impedance) in an alarmed condition.

⑤ Alarm immunity time

Set the delay time [in sec] from the moment the flowrate exceeds the alarm set value to the moment

an alarm is activated. Remember that setting of this parameter is common to both alarms 1 and 2.

(2) Setting up the low alarm

Parameters related to the low alarm come in the following six. Set each of them by referring to the

description given for individual parameters.

CAUTION:

① Alarm setpoint

Set the flowrate [(L/min (normal)) to be at the low alarm.

② Alarm hysteresis

Alarm is cancelled when the following condition is met. Select the appropriate alarm hysteresis [L/min

(normal)].

Flowrate > Alarm setpoint + Alarm hysteresis

If variation in flowrate is excessive, resulting in frequent alarm ON - OFF cycling, set a little larger

value.

③ Alarm status (higher digit)

Setting is to be made on the low alarm: set "L" to the higher digit.

Remember that at "0" flowrate, the alarm is disabled.

④ Alarm status (lower digit)

Set up the output status to the lower digit in an alarmed condition.

Selecting "S" results in an "ON" output (Lo impedance) in an alarmed condition.

Setting "o" results in an "OFF" (Hi impedance) in an alarmed condition.

⑤ Lower limit in the alarm immunity range

Set up the lower limit of flowrate [L/min (normal)] at which an alarm is activated.

In a line where multiple pneumatic equipment are in use, for example, certain equipment may have

leaks more or less, such as bleed type reducing valves, even when the system has been shut down.
By establishing a lower limit in the "alarm immunity range", this monitor can prevent the alarm from
being activated in a situation like this. While the following condition continues, the low alarm remains
inoperative:

Flowrate ≦ Low alarm in the alarm immunity range

Select a little larger setpoint than that at the system shutdown.

CAUTION:

Below the cutoff level [L/min (normal)], the monitor finds the flowrate

as "0". This requires setting up the lower limit in the alarm immunity
range to a value larger than the cutoff level and, at the same time,
smaller than the alarm setpoint. If a value larger than the alarm setpoint
is selected, priority is given to the lower limit in the alarm immunity
range: setting the low alarm setting then does not make any sense.

⑥ Alarm immunity time

Set the delay time (in sec) from the moment the flowrate reaches the alarm setpoint to the moment

an alarm is activated. At system shutdown, an alarm is normally not activated because the flowrate
falls below the lower limit in the alarm immunity range; at system startup, on the other hand, an alarm
remains inoperative because the flowrate exceeds the alarm setpoint. However, at the transition
from system shutoff to system startup, and vice versa, the monitor initiates an alarm momentarily. A
solution to get around this problem at system startup and at shutdown is to select a setting longer
than the duration of the alarmed condition. Remember that setting this parameter is common to both
alarms 1 and 2.

8.6 Dummy Pulse Output

Thanks to the dummy pulse output feature, the monitor can provide a 10Hz simulated pulse output irrespective of
actual flowmeter operation. And it counts the number of pulses so produced on the total counter. With this feature,

you can easily run a connection and performance check between this monitor and other systems coupled.

Given below is the procedure to use this output. ("X" and "Y" represent numerical values of setting.)

CAUTION:

(1) Select Dummy pulse output.

Flowrate

MODE

Press

When this feature is enabled, the monitor produces a train of dummy pulses
irrespective of actual flowrate. In applications where the flowmeter output is

used as control data, this operation should be avoided, however. Incidentally,
dummy pulse accuracy is ±1 count with respect to the indicated reading.

becomes a blinking "20.00" and the transmitter produces an analog output
adjusted based on the established numerical value. If a deviation of analog
output is still large, repeat the procedure to set the numerical value.

error

Fails to produce
pulses properly.

Analog error More than 115%

of analog full scale
value is flowing
due to excessive
flowrate or the like.

Make sure of the following three:

• Pulse weight (parameter)

• Pulse "ON" duration (parameter)

• Instant flowrate while an error message ap­pears.

Select parameters such that the parameters
and variable above meet the following condi­tion:
Flowrate with error message [L (normal)]
/pulse weight [L/min (normal)]
× (pulse "ON" duration [msec] + 1)
/60 < 1000

Take the following countermeasures.

• Lower the flowrate.

• Increase the set value of analog full-scale
value (parameter).
