3.1 Incoming acceptance, transport and storage

3.1.1 Incoming acceptance

On receipt of the goods, check the following:
• Check the packaging and the contents for damage.
• Check the shipment, make sure nothing is missing and that the scope of supply matches your
order.

3.1.2 Transport

The following instructions apply to unpacking and to transporting the device to its final location:
• Transport the devices in the containers in which they are delivered.
• Do not remove the protective plates or caps on the process connections until you are ready to
install the device. This is particularly important in the case of sensors with PTFE linings.
Special notes on flanged devices
Caution!
"
• The wooden covers mounted on the flanges from the factory protect the linings on the flanges
during storage and transportation. In case of Promag L they are additionally used to hold the lap joint flanges in place. Do not remove these covers until immediately before the device in the pipe.
• Do not lift flanged devices by the transmitter housing, or the connection housing in the case of
the remote version.
#
Transporting flanged devices DN 300 (12")
Use webbing slings slung round the two process connections. Do not use chains, as they could damage the housing.
Warning! Risk of injury if the measuring device slips. The center of gravity of the assembled measuring device might be higher than the points around which the slings are slung. At all times, therefore, make sure that the device does not unexpectedly turn around its axis or slip.

3.1.3 Storage

Please note the following:
• Pack the measuring device in such a way as to protect it reliably against impact for storage (and transportation). The original packaging provides optimum protection.
• The storage temperature corresponds to the operating temperature range of the measuring transmitter and the appropriate measuring sensors ä 99.
• Do not remove the protective plates or caps on the process connections until you are ready to install the device. This is particularly important in the case of sensors with PTFE linings.
• The measuring device must be protected against direct sunlight during storage in order to avoid unacceptably high surface temperatures.
• Choose a storage location where moisture does not collect in the measuring device. This will help prevent fungus and bacteria infestation which can damage the liner.

Install a siphon or a vent valve downstream of the sensor in down pipes whose length h 5 m (16.4 ft). This precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring tube. This measure also prevents the system losing prime, which could cause air pockets. Information on the lining's resistance to partial vacuum can be found on ä 103.

3.2.3 Orientation

An optimum orientation position helps avoid gas and air accumulations and deposits in the measuring tube. However, Promag offers the additional Empty Pipe Detection (EPD) function to ensure the detection of partially filled measuring tubes, e.g. in the case of degassing fluids or varying process pressure:
• Electrode Cleaning Circuit (ECC) for applications with accretive fluids, e.g. electrically conductive deposits ("Description of Device Functions" manual).
• Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes, e.g. in the case of degassing fluids (ä 73)
• Exchangeable Measuring Electrodes for abrasive fluids (ä 92)
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction with Empty Pipe Detection.
Fig. 10: Vertical orientation
Horizontal orientation
The measuring electrode plane should be horizontal. This prevents brief insulation of the two measuring electrodes by entrained air bubbles.
Caution!
"
Empty Pipe Detection functions correctly only when the measuring device is installed horizontally and the transmitter housing is facing upward (å 10). Otherwise there is no guarantee that Empty Pipe Detection will respond if the measuring tube is only partially filled or empty.

3.2.5 Foundations, supports

If the nominal diameter is DN 350, mount the sensor on a foundation of adequate load-bearing strength.
Caution!

3.2.6 Adapters

Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor in larger­diameter pipes. The resultant increase in the rate of flow improves measuring accuracy with very slow-moving fluids. The nomogram shown here can be used to calculate the pressure loss caused by reducers and expanders.
Note! The nomogram only applies to liquids of viscosity similar to water.
1. Calculate the ratio of the diameters d/D.
2. From the nomogram read off the pressure loss as a function of flow velocity (downstream from
the reduction) and the d/D ratio.

3.2.7 Nominal diameter and flow rate

The diameter of the pipe and the flow rate determine the nominal diameter of the sensor. The optimum velocity of flow is between 2 and 3 m/s (6.5 to 9.8 ft/s)
The velocity of flow (v), moreover, has to be matched to the physical properties of the fluid:
• v < 2 m/s (v < 6.5 ft/s): for abrasive fluids
• v > 2 m/s (v > 6.5 ft/s): for fluids producing buildup
!
Note! Flow velocity can be increased, if necessary, by reducing the nominal diameter of the sensor (ä 17).

3.2.8 Length of connecting cable

In order to ensure measuring accuracy, comply with the following instructions when installing the remote version:
• Fix cable run or lay in armored conduit. Cable movements can falsify the measuring signal especially in the case of low fluid conductivities.
• Route the cable well clear of electrical machines and switching elements.
• Ensure potential equalization between sensor and transmitter, if necessary.
• The permitted connecting cable length L
is determined by the fluid conductivity (å 16).
max
A minimum conductivity of 20 μS/cm is required for measuring demineralized water. Most liquids can be measured as of a minimum conductivity of 5 μS/cm.
• The maximum connecting cable length is 10 m (32.8 ft) when empty pipe detection (EPD ä 73) is switched on.

3.3.3 Installing the Promag W sensor

!
"
Note! Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the customer.
The sensor is designed for installation between the two piping flanges.
• Observe in any case the necessary screw tightening torques on ä 27
• If grounding disks are used, follow the mounting instructions which will be enclosed with the shipment

Fig. 19: Installing the Promag W sensor
Seals
Comply with the following instructions when installing seals:
• Hard rubber lining additional seals are always necessary.
• Polyurethane lining no seals are required.
• For DIN flanges, use only seals according to EN 1514-1.
• Make sure that the seals do not protrude into the piping cross-section.
Caution! Risk of short circuit! Do not use electrically conductive sealing compounds such as graphite! An electrically conductive layer could form on the inside of the measuring tube and short-circuit the measuring signal.
Ground cable
• If necessary, special ground cables for potential equalization can be ordered as an accessory (ä 76).
• Information on potential equalization and detailed mounting instructions for the use of ground cables can be found on ä 55
Screw tightening torques (Promag W)
Please note the following:
• The tightening torques listed below are for lubricated threads only.
• Always tighten the screws uniformly and in diagonally opposite sequence.
• Overtightening the screws will deform the sealing faces or damage the seals.
• The tightening torques listed below apply only to pipes not subjected to tensile stress.
