How to use these installation and operating instructions

Congratulations on purchasing this high quality product. To get the best out of your mass flowmeter,

please take some time to read through the instructions.

This instruction handbook is comprehensive and describes the many features and options available

with this mass flow meter.

Please refer to the index for a list of detailed topics.

Note:

If applicable, a separate document is supplied that describes all ATEX hazardous area information.

Product liability and warranty

The OPTIMASS mass flow meter family is designed for the direct measurement of mass flow rate,

product density and product temperature, and also indirectly enables measurement of parameters such

as total mass, concentration of dissolved substances and the volume flow.

For use in hazardous areas, special codes and regulations are applicable which are specified in the

section on Hazardous Area Installations.

Responsibility as to suitability and intended use of our instruments rests solely with the

purchaser. The supplier does not accept any liability resulting from misuse by the customer.

Improper installation and operation of the flow meters may lead to loss of warranty. Warranty is also

null and void if the instrument is damaged or interfered with in any way.

In addition, the “general conditions of sale” which forms the basis of the purchase agreement are

applicable.

If you need to return OPTIMASS flow meters to KROHNE, please complete the form on the last page

of the installation and Operating manual and return it with the meter to be repaired. KROHNE regrets

that it cannot repair or check your flow meter unless accompanied by this completed form.

CE / EMC Standards /Approvals

• The OPTIMASS family with the MFC 050 / 051 / 010 signal converter meets all the requirements of

the EU-EMC and PED Directives and bears the CE Symbol.

• The OPTIMASS system is approved for hazardous duty installations to the harmonised European

Standards (ATEX) to Factory Mutual (FM) and CSA (Canadian Standards).

Installation and Operating Instructions OPTIMASS 5

Unpacking the meter

When unpacking your meter, please ensure that no visible damage has occurred during

transportation. If damage has occurred, please contact the carrier for claims.

Your high quality instrument has been fully tested and checked before shipping. The following

items should be included with your instrument unless otherwise requested:

1. Mass Flow Meter OPTIMASS

2. Separate Converter with remote converter wall mount (not for compact version)

3. CD-ROM & Quick Start Guides

4. Spanner to open the electronic housing lids

5. Bar magnet for programming the meter

6. Screw driver for terminal connections

7. Calibration certificate

8. Factory and Material certification, if ordered.

If any of these items are missing, please contact your nearest KROHNE Office or representative

(see back page).

Attention:

Please read the Handbook before installing the meter.

Many problems are avoided when the simple guidelines in this handbook are followed.

Installation and Operating Instructions OPTIMASS 6

1 Mechanical Installation

1.1 General principles

The OPTIMASS mass flow meters provide high accuracy and excellent repeatability. Narrow band pass

digital filtering, and the mathematically modelled internal primary head design with AST (Adaptive Sensor

Technology) for the OPTIMASS sensor family provide exceptional immunity to external vibratory

disturbances from nearby process equipment.

The accuracy of the flow meter is not affected by velocity profile.

The following installation guidelines are practical to implement, particularly if planned before the

OPTIMASS meter is first installed. For further dimensions or connections, please refer to the relevant

section.

For the OPTIMASS, in general, no special mounting requirements are necessary. However, good general

engineering practice for the installation of flow meters should still be observed.

The general guidelines described in this section are valid for the complete OPTIMASS family of mass flow

meters.

• The mass flow meters do not require any straight inlet or outlet runs.

• Due to the weight of the meters we recommend the use of supports.

• It is permissible to support the body of the meter.

• The meter can be installed horizontally, in an upward sloping pipeline or vertically. For best results, a

vertical installation with flow in an upward direction is recommended.

This label on the meter shows the flow direction programmed into the converter in function 3.1.4.

As default this is always in the direction of the ‘+’ arrow, i.e. left-to right as the label is viewed.

Installation and Operating Instructions OPTIMASS 7

Examples

Vertical mounting Horizontal mounting

Upward sloping installation

Avoid mounting the meter with long vertical

drops after the meter. This could cause

siphoning and cause measurement errors.

Avoid mounting the meter at the highest point in

the pipeline. Air or gas can accumulate here and

cause faulty measurements

Flow

1 Valve for zeroing flow meter

2 The second valve is recommended if the pump is switched off to prevent reverse flow

To enable a good zero to be done, it is recommended that a shut-off valve be installed downstream

of the flow meter.

Installation and Operating Instructions OPTIMASS 8

1.1.1Transport and Lifting

As the larger meters are heavy, care should be taken when lifting to install.

• Meters should be lifted or suspended using a well maintained sling.

• The meters should under no circumstances be lifted by the electronics housings.

• The meters can be lifted and suspended from the spigots as shown.

Installation and Operating Instructions OPTIMASS 9

1.2 OPTIMASS 7000 Single Straight Tube Meter

1.2.1 Specific Installation Guidelines

• Tighten flange bolts evenly.

• Observe min and max pipe end loads at end of this section.

The use of reducers at the flanges is

allowed. Extreme pipe size reductions

should be avoided due to possibility of

cavitation and degassing.

There are no additional installation requirements for the OPTIMASS 7000 sensors. Fixing of flexible

hoses directly on the meter is allowed.

1.2.2 Ambient / Process temperatures

The specified and approved ambient and process temperatures must be observed.

Note:

Where meters are mounted in direct sunlight, it is recommended to install a sunshade. This is

particularly important in countries with high ambient temperatures.

The maximum differential temperature between the process and ambient temperature without

insulation is 130°C or 265°F for Titanium and 80°C or 115°F for Hastelloy and Stainless Steel meters.

1.2.3 Pressure Equipment Directive (PED) requirements.

To comply with the requirements of the PED in Europe, the following information is provided to assist

the plant engineer in installing the meter.

Measuring tube: Titanium Grade 9 Sealing Faces: Titanium Grade 2

Hastelloy C22 Hastelloy C22

Stainless SS 318 Stainless SS 318

The outer cylinder (Secondary Pressure containment) 304 / 304L is dual certified and with “0” rings in

pairs of Viton and hydrogenated nitrile. (Optional outer cylinder of 316/316L).

Wiring feedthrough is made of Epoxy.

Flanges all 316 / 316 L dual certified.

Optional heating jacket 316 / 316L.

Note :

Outer cylinder is in contact with heating medium.
