1. PRODUCT OUTLINE

1.1. Outline

This high precision flowmeter is the world’s first clamp-on type ultrasonic flowmeter that adopts the pulse Doppler method and the transit time method as its measurement principles. The ultrasonic flowmeter for industrial use employs the pulse Doppler method, which directly measures flow distribution, thus easing straight pipe conditions and allowing measurement of flows that have not grown into eddy or laminar flow. Combined use of the transit time method allows the hybrid ultrasonic flowmeter to be used for measuring a significantly wide range of liquids. The pulse Doppler method, which uses echoes coming from reflectors in a liquid to be measured, is ideal for the measurement of liquids that contain air bubbles and particles. On the other hand, the transit time method, which allows ultrasonic waves to pass through for measurement, is ideal for the measurement of clean liquids. The new hybrid technique employing both the pulse Doppler and the transit time methods allows the flowmeter to be used for wider range of applications. In addition, our self-developed switching algorithm ensures automatic switching between the two methods depending on the conditions of a liquid to be measured (such as mixing status of air bubbles or particles and flow rate), thus facilitating measurement.

1.1.1. Measurement principle

The pulse Doppler method measures flow distribution and flow rate based on the fact that Doppler frequency of the

•

echo coming from reflectors such as air bubbles and particles in liquids changes with fluctuation of flow rate.

3.3. Flow transmitter wiring

3.3.1. Cautions in wiring

CAUTION

(1) Use a dedicated cable (FLY) as a signal cable between the detector (FSW) and the flow transmitter

(FSH). Do not join cable in the middle.

(2) Be sure to let the signal cables installed between the detector and the flow transmitter run through a

metal conduit tube. The signal cables for upper and the lower streams can be made to run through the conduit tube together. However, do not let the power cable run through the conduit tube

together with the signal cables to avoid induction problems. (3) Use shielded cables for output signals as far as possible. (4) To prevent noise from coming in, avoid installing wiring in a duct together with the power cable. (5) Directly ground the power cable that includes a ground lead. (6) The flowmeter is not equipped with a power switch. Mount one separately. (7) Tightly seal the unused wiring ports with supplied sealing caps.

3.3.2. Applicable wires

Use the following cables.

Power cable:

•

3-wire or 2-wire cabtyre cable

Nominal sectional area: 0.75 mm Finished outer diameter: φ11 mm

Output signal cable:

•

2-wire or multi-wire cabtyre cable as required

Finished outer diameter: φ11 mm

Cable between detector and flow transmitter:

•

Cable for ultrasonic wave signals (High-frequency coaxial double shield cable with characteristic impedance of 50 Ω, With waterproof BNC connector provided on one side)

Finished outer diameter: φ7.3 mm

Cable for temperature sensor (3-wire shielded cable, With waterproof connector provided on one side)

Finished outer diameter: φ6.9 mm

or more

3.3.3. Treatment of wiring port

The casing of the flow transmitter is of watertight type (IP67). However, to prevent entry of moisture and occurrence of condensation, airtight processing of wiring ports is required. Be sure to take measures against entry of water using the waterproof glands supplied with the instrument. Tightly seal unused glands using the supplied sealing caps.

CAUTION

Do not install the flow transmitter in a place subject to the occurrence of flooding.

4.4.9.2. Setting total pulse (Total rate, pulse width)

Description

The measurement value (flow rate) can be integrated in response to the total pulse output from an integrating meter, etc. as follows. (1) Total rate: When the total volume reaches the value specified by the total rate, the total pulse value on the

measurement screen is added, and 1 pulse is output for total pulse (volume). (Setting range) 0 to 999999.999)

(2) Pulse width: The pulse width can be selected with the connected counters DO1/DO2 and DO3.

Set the pulse width when “F: TOTAL PULSE” or “R: TOTAL PULSE” is used in status output setting.

Pulse width 1: Pulse width of DO3 (relay contact). Select one from the following.

•

50 msec, 100 msec, 200 msec

Pulse width 2: Pulse width of DO1/ DO2 (transistor open collector). Select one from the following.

•

0.5 msec, 1.0 msec, 2.0 msec, 5.0 msec, 10.0 msec, 20.0 msec, 50.0 msec, 100.0 msec,

200.0 msec Note: If the total rate is set to “0,” the total pulse is not output. Note: Set the total pulse in a state where the total mode is in total stop state.

Limitation in setting

The following limitations are imposed on the total pulse output.

DO output port

DO1/DO2: Transistor open collector

DO3: Relay contact 1 pulse/sec or lower 50msec, 100 msec, 200 msec

The maximum output frequency is limited depending on the pulse width setting. Set the total rate and the pulse width so that the following conditions 1 and 2 are satisfied. Otherwise, proper operation may not be assured.

Condition 1:

Condition 2:

Flow rate span

*1) Full scale 1 or full scale 2, whichever is larger, in the case of auto 2 range, bi-directional range, and bi-directional

auto 2 range setting The limitation of the maximum output frequency of each DO output port is applicable when the flow rate exceeds the set range. Consequently, if the setting is made so that the maximum frequency is obtained at 100% flow rate, the flow rate exceeding 100% does not allow the total pulse output to follow. If the over range continues for a long time, accurate total value may not be obtained. If there is a possibility that the flow rate may exceed 100%, review the range and the total rate, and make the setting so that the maximum frequency is kept below the limit.

Example of calculation

Find the total rate settable range under the following range and pulse width. When the range and the pulse width settings are as follows: Full scale: 36 [m
