1. General presentation

The measuring chain is composed of two indissociable elements : the sensor and the electronic

processor.

1.1. The sensor

Each sensor is matched with its own electronics. Before switching on, be sure that serial

numbers at the sensor and the electronics identification plates are corresponding.

The operation principle of the equipment makes that the provided viscosity information is

relative : in the same fluid, at the same conditions the information is the same. But for 2 rheologically

different fluids the response can be different (despite it is perfectly repeatable).

The sensor active part is protected by an stainless tube which must not be removed.

The sensor is fixed upon its mounting flange by means of the provided 4 long screws.

See the detailed leaflet, § 2.

1.2. The processor

Its functions:

- Powers the sensor,

- Processes the sensor’s information,

- Displays and transmits the process information : viscosity, temperature,

sensor’s frequency, outputs and relays states….

The processor is composed of two modes :

“UTILISATION” Mode :

The “UTILISATION” Mode makes it possible to visualize in different forms viscosity and

temperature values.

- Visualization with bargraphs, acquisition graph

- Access to the sensor identification data

- Access to the “ADAPTATION” Mode blocks starting from the principal menu

“ADAPTATION” Mode :

The “ADAPTATION” Mode makes it possible to adapt the displayed data, parameters, settings

and configuration of the processor according to the using conditions.

- Display block : makes it possible to display outputs and relays states, rough data, to

choose viscosity and temperature units and to choose the viscosity correction to active.

- Settings block : makes it possible to set current outputs, alarms, bargraphs and graph

scales, to choose and set the modalities parameters of kinematic viscosity calculation, to

proceed to the mounting offset adjustment, to activate and define viscosity filter and to

change the Pt100 status.

- Parameters block : makes it possible to parameter viscosity corrections, to read and

modify the compensation table, to modify security codes and to set the density coefficient.

- Configuration block : makes it possible to SOFRASER to configure the processor with the

manufacturing data (thermal drift, calibration) and to define the viscosity adjustment data.

1.3. Checking the equipment at the receipt

a) At first, check the supply conformity with the ordered equipment, mainly the presence of the

parts necessary for the equipment mounting. Those to be used at the process will be given to

the concerned department, for the installation preparation.

b) Place the sensor on a soft foam plate, connect it to processor (see §3.10) and switch on. The

vibration appears at the rod, the viscosity indication is close to zero (or close to the minimal

required current value of the analog output). When touching the rod, the information has to

increase.

In case of subnormal operation a) or b), check as follows :

Power supply, connections, cables,

The good condition of the vibrating rod (no bending on knock damages).

Consult your distributor.

1.4. Checking the equipment when placed at the process

Before filling the network check that the viscosity information is stable (vibrating rod in air). If

not, check the strength of the sensor fitting, then rotate the sensor of 90° (4 possible positions).

Choose the position where the information is the most stable.

Locate this position, in order to restore it when the sensor is removed – put in place.

Adjust the mounting offset, at room temperature. The rod is vibrating in air.

When possible, note the viscosity information when a cleaning or rinsing solution is flowing.

If the original calibration is convenient, one of the 2 above mentioned values can be taken as

reference for periodic control of the equipment operation each time that the same conditions will occur

(rod in air, or in the cleaning solution). Such an operation can be assimilated to a self-checking.

If the original calibration has been modified the reference values will be of course those

obtained with the new calibration.

1.5. Periodic checking

Conformity to regulations relative to Quality Insurance implicates a periodic control of the

measuring equipment used in the manufacturing operations, taking in consideration (or correcting)

their drift in time.

It is proved that this equipment drift is negligible. However, it is good to check their aspect and

their response once a year, at the same time as the other process equipment.

A fast test is many times available, when the sensor active part is in air, or immersed in a

cleaning or rinsing solution. As long as these values stay similar, we can say that the sensor

operation is right among its whole range (if no intermediate re-programming occurred).

1.5.1. Offset adjustment in air

The clean and dry rod is vibrating in air when the offset adjustment is carried out.

The amplitude, corrected in offset, Vbrut, must be shift to the reference of 900 mV.

See User Manual §5.1.

Technical Manual MIVI 9612

Réf. 254-31/0 7

1.5.2. Modification of the previous calibration

The device has been programmed in order to answer to your needs. These features

programming steps are noticed on the features specification pages at the end of this document.

At first, be sure that the modification is necessary, and not consecutive of a non

coherent comparative information (different measuring conditions, bad standards, inaccurate

or wrong laboratory measurements,…).

The calibration parameters are protected and can only be modified with the security code.

For modifications of calibration, contact your distributor.

1.6. Directives and Standards

1.6.1. Certification ATEX

MIVI sensors are in agreement with 94/9/EC directive (ATEX) for equipments installed in

explosive gas atmospheres or in presence of combustible dust :

II 2G (gas) or II 2D (dust)

Ex d IIC T1 to T6 : gas

Ex tD A21 IP67 T75°C, T90°C, T125°C, T190°C, T290°C, T300°C : dust

Be sure the sensor’s certification is in accordance with the security level required on your

process location : Area classification, equipments group, protection method, gas type, temperature

codes…

Area classification and equipments installation rules are detailed into IEC 7910 and EN 60 079

standards for gas or EN 61 241 standards for dust.

To always keep the maximum security level of the viscometer, don’t open it. Furthermore, we

advice to install the sensor with the cable gland orientated to the floor.

Check periodically information indicated on the sensor’s identification plate are still visible.

1.6.2. Installation in hazardous area

Here are the possible ways to install MIVI 9601sensors in hazardous area.

1.6.3. European Pressure Equipment Directive

Up to 60 bars, MIVI sensors are in agreement with the article 3.3 of the PED 97/23/EC. In case

of higher pressure, sensors are certified one by one.

The mounting flange is an accessory to be welded on the process line. It means it can not be

individually certified but with the whole process line.

1.6.4. EMC and low voltage directive

The processor 9601 is in agreement with EMC specifications detailed into 89/336/EEC

(modified by 92/31/EEC and 93/68/EEC).

Processors 9601 are supplied by 24 VDC. So they are not subjected to the Directive Low

tension 73/23/CEEC (modified by 93/68/CEE).

MIVI sensors have been designed and manufactured according to the electrical safety rules.

2.Viscosity sensor

2.1. Various models

•

General-purpose sensors.

•

Sanitary sensors.

•

Ex-proof sensors (ATEX, FM, JIS).

•

High pressure sensors (up to 150 bars).

•

Special models, according to the requirements (material and design).

•

When required, a temperature probe can be incorporated to the MIVI sensor.

2.2. Sensor installation

It operates at any position, even upside down. Its active part has to be permanently immersed in

the fluid (low part of the network or reactor). If the fluid temperature varies widely and fast, choose the

upside down or horizontal position, in order to allow a convenient air convection among the sensor

body.

It is screwed to its mounting flange by means of 4 screws M6X100 (or 8 screws M8 for high

pressures). The mounting flange has to be welded close to the device generating the viscosity

variations (heater, mixer, reactor, etc…). Retention, high flow velocities, strong vibrations and high

magnetic fields have to be avoided.

According to the application the mounting flange material can be :

Stainless steel Z3CND 17/11-02 (316L).

Carbon steel XC38.

Other materials, according to the requirement.

2.2.1. Elbow mounting

•

The flange is welded on a right angle tee as indicated in

pic.1.

•

The minimal pipe diameter is of 32 mm.

•

The flange and the pipe axes have to be the same.

•

The flow direction is as indicated on fig.1 (unless for

fibrous fluids where the flow is inverted and the rod

protector removed. (See §2.2.5).

•

A free area of at least 150 mm length is necessary.

Advice : choose a sensor position in order to assure a

permanent fluid renewal and to avoid the existence of

“dead zone”.

2.2.2. Plane side mounting

•

The flange is welded on a metal plate as indicated on

pic.2.

•

The free area around the vibrating rod has to be at least

∅40, 150 mm length.

•

In order to avoid parasitic vibrations, the plate where the

flange is welded must be thicker than 5 mm.

Advice : preferably choose a sensor position with the rod

to the top in order to have a total immersion of the

vibrating rod and to avoid the formation of “dead zone“.

2.2.3. Pot mounting, for small flow rates, or pilot plant

See picture 3.

2.2.4. Special mountings

The small sensor size allows numerous personalization

of its fitting according to the user's requirements. Consult

your distributor.

2.2.5. Replacement cap

Each mounting flange is provided with an obturation kit :

Cap and O-ring

4 fixing screws CHC M6 (or 8 fixing screws M8 for high
