|
|
1.4 Pressure Equipment Directive (PED)
LEGAL NOTICE!
The Pressure Equipment Directive places legal requirements on both the manufacturer and the end user. Please read this section carefully!
Visual check
XXXXX |
To ensure the PED integrity of the meter, you MUST check that the serial numbers on the converter nameplate and the sensor nameplate are the same.
To comply with the requirements of the Pressure Equipment Directive (PED) the manufacturer provides all the relevant technical data in the technical data section of this handbook. In addition to which, the following should also be noted:
•Secondary pressure containment is NOT supplied as standard.
•The non PED / CRN approved outer cyclinder has a typical burst pressure greater than 100 barg / 1450 psig at 20°C / 68°F.
•The wiring feedthrough is made of Epoxy, PPS or PEEK with two O-rings made from FPM / FKM & Hydrogenated Nitrile.
•If the measuring tube/s fails, the O-ring and feedthrough will be in contact with the process product.
•You MUST make sure that the O-ring ring and feedthrough material is suitable for the application.
•Alternative O-ring materials are available on request.
Secondary pressure containment
Where the meter is being used to measure high pressure gases and / or gases kept as liquids by high pressure and / or where there is a risk of tube failure because of the use of corrosive or erosive fluids, frequent pressure and / or thermal cycling, seismic or other shock loading, a secondary containment option MUST be purchased
Where the above situation applies and the process pressure exceeds the secondary pressure containment (please refer to technical data) or where secondary pressure containment is not available, the burst disc option MUST also be purchased. For more information, please contact your nearest representative.
DANGER!
If it is suspected that the primary measuring tube has failed, de-pressurise the meter and remove it from service as soon as it is safe to do so.

1.5 Dirty gas
Dirty gas is gas that carries sand or other solid particles. Dirty gas causes excessive wear to the primary measuring tube that can eventually result in complete tube failure. In some situations tube failure where gas is being measured, can be very dangerous.
DANGER!
If the meter is being used to measure gas and there is a risk that the gas might be dirty, you must fit a filter upstream of the meter to catch solid particles.

3The 11864-2 Form B is not supplied as part of this connection but it can be ordered.
2.2Nameplates
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate.
2.3 CSA dual seal
To comply with the requirements of ANSI/ISA -12.27.01-2011 “Requirements for process Sealing Between electrical systems and Flammable or Combustible process Fluids” a secondary seal is incorporated into all OPTIMASS / GAS products. If the primary seal fails, the secondary seal will prevent escaping fluid reaching the electronic compartment.
Pressures and / or temperatures are limited by tube, temperature, connection and Ex limits. Check the meter nameplates and relevant documentation for full details. On all meters operating on gas measurement, the casing of the meter is fitted with a burst disc. If the primary seal (tube) fails leakage will occur from the burst disc. Install the meter so that the burst disc is pointing away from personnel.
Liquids (Example model code: OPTIMASS 2400C S250 - LIQUID)
Pressure and temperature data:
OPTIMASS 2400C -45°C...+130°C and 100...14000 kPa
If the primary seal fails, the casing of the meter will fill with liquid and the meter will stop working. The meter will notify the operator by displaying the ststus message "Sensor: Sensor signal low" on the converter or PLC display. This is an indication that the primary seal (tube) has failed and the status of the meter should be checked.
Meter status:
The meter will also display the mesage "Sensor: Sensor signal low" if the measuring tubes are not completely filled with fluid. For example, if the meter is drained or re/filled.
To check the status of the meter, drain and re/fill with fluid and note the converter or PLC display. See the relevant section of the converter handbook for a list of status messages and diagnostics information.

DEVICE DESCRIPTION 2 |
|
OPTIMASS 2400 |
|
|
|
|
If the meter continues to display the message: "Sensor: Sensor signal low" you MUST assume that the primary seal (tubes) has failed and the appropriate action MUST be taken.
Gases (Example model code: OPTIMASS 2400C S250 - GAS)
Pressure / temperature data:
OPTIMASS 2400 -45°C...+130°C and 500...14000 kPa
Pressures and/or temperatures may be further limited by tube, temperature, connection and Ex limits. Consult the meter nameplate and relevant documentation for full details.
On all meters operating on gas measurement the casing of the meter is fitted with a burst disc. If the primary seal (tube/s) fails leakage will occur from the burst disc. Install the meter so that the burst disc is pointing away from personnel.
Regular maintenance of the burst disc:
Carry out regular maintenance checks on burst discs for leakage and/or blockages. On all OPTIMASS meters, the primary seal is considered to be the measuring tube of the meter. The materials of construction of the measuring tube/s are described within the relevant sections of this handbook and the customer’s product and any other fluid flowing through the tube must be compatible with the material of construction. If failure of the primary seal is suspected then the process line should be de-pressurised and the meter removed as soon as it is safe to do so. Please contact customer service for servicing or replacement of the meter.
2.4 Temperature differential and thermal shock
Temperature differential
The maximum difference between ambient temperature and process (operating) temperature is 100°C / 212°F.
Thermal shock
Thermal shock occurs when there is a sudden and extreme change (shift) in process temperature. To avoid thermal shock, refer to the following table for the maximum temperature shift.
Meter |
Maximum temperature shift |
|
|
S100 |
+90°C / +194°F (+110°C / +230°F with a maximum operating pressure of 40 barg / 580 psig) |
S150 |
+80°C / +176°F |
S250 |
+50°C / +122°F |
CAUTION!
Operation outside these limits may result in shifts in density and mass flow calibration. Repeated shocking may also lead to premature failure of the meter! However, higher thermal shocks are possible at lower working pressures. For more information, please contact your nearest representative.
