OPTIMASS 3400

1 Measuring tube 2 Drive coils 3 Sensor 1 4 Sensor 2

Static meter not energised and with no flow

1 Measuring tube 2 Drive coils 3 Sensor 1 4 Sensor 2

A Coriolis single Z tube mass flowmeter consists of a single Z shaped measuring tube (1) two drive coils (2) and two sensors (3 and 4) that are positioned either side of the drive coils.

OPTIMASS 3400

Energised meter

1 Measuring tube 2 Direction of oscilation 3 Sine wave

When the meter is energised, the drive coils vibrate the measuring tube causing it to oscillate and produce a sine wave (3). The sine wave is monitored by the two sensors.

PRODUCT FEATURES

Energised meter with process flow

1 Process flow 2 Sine wave 3 Phase shift

When a fluid or gas passes through the tube, the Coriolis effect causes a phase shift in the sine wave that is detected by the two sensors. This phase shift is directly proportional to the mass flow.

Density measurement is made by evaluation of the frequency of vibration and temperature measurement is made using a Pt500 sensor.

• ASME flange ratings are based on ASME B16.5 2003 table 2 material group 2.2

• JIS flange ratings are based on JIS 2220: 2001 table 1 division 1 material group 022a

Notes

• The maximum operating pressure will be either the flange rating or the measuring tube rating, WHICHEVER IS THE LOWER!

• The manufacturer recommends that the seals are replaced at regular intervals. This will maintain the hygienic integrity of the connection.

INSTALLATION

3.1 Intended use

This mass flowmeter is designed for the direct measurement of mass flow rate, product density and product temperature. Indirectly, it also enables the measurement of parameters like total mass, concentration of dissolved substances and the volume flow. For use in hazardous areas, special codes and regulations are also applicable and these are specified in a separate documentation.

Responsibility for the use of the measuring devices with regard to suitability, intended use and corrosion resistance of the used materials against the measured fluid lies solely with the operator.

This device is a Group 1, Class A device as specified within CISPR11:2009. It is intended for use in industrial environment. There may be potential difficulties in ensuring electromagnetic compatibility in other environments, due to conducted as well as radiated disturbances.

The manufacturer is not liable for any damage resulting from improper use or use for other than the intended purpose.

3.2 Plastic Inserts

Figure 3-1: Base plate plastic inserts

The four mounting holes in the meter base plate are fitted with plastic inserts. Do not remove the inserts prior to installation.

3.3 Meter support

Use the base plate to mount and fully support the weight of the meter.

INSTALLATION

DO NOT use the process pipework to support the weight of the meter. This will cause severe damage.

3.4 Two hole mounting

Figure 3-2: Using two holes to mount the meter

1 It is recommended that ALL four mounting holes are used to secure the meter. 2 It is possible to secure the meter using only two of the mounting holes.

3.5 Horizontal mounting

Mount the meter on a firm, rigid base.

DO NOT mount the meter upside down.

3.6 Vertical mounting

If the meter is mounted vertically, the process flow MUST be upwards.

3.7 Self draining

3.8 Purge ports

Purge ports

Purge portsPurge ports

• Meters ordered with purge port option, will be fitted with ¼" NPT female connections

• The NPT connections are sealed with NPT plugs and PTFE tape

DO NOT REMOVE THE NPT plugs! The meter is factory sealed and filled with dry nitrogen gas. If you remove the plugs and allow moisture to get into the meter it will cause damage. If you think that the measuring tube has failed, depressurise the meter (when it is safe to do so) and remove the plugs. Purge the meter case to remove the process product.

Burst discs

Burst discsBurst discs

• If the operating pressure is higher than the design pressure of the secondary containment you MUST order the burst disc option.

• The disc failure pressure is 20 barg at 20ºC / 290 psig at 68ºF.

• If process conditions change from the original order, you MUST contact the manufacturer for

advice regarding the suitability of the fitted disc.

• If the process product is hazardous, it is recommended that an exhaust tube is fitted to the NPT male thread so that the discharge can be piped to a safe area.

• Make sure that the arrow on the burst disc is pointing away from the meter.
