Proline Prosonic Flow 93	Safety instructions

1 Safety instructions

1.1Designated use

The measuring device described in these Operating Instructions is to be used only for measuring the flow rate of liquids in closed pipes.

Examples:

•Acids, alkalis, paints, oils

•Liquid gas

•Ultrapure water with low conductivity, water, wastewater

As well as measuring the volume flow, the sound velocity of the fluid is also always measured. Different fluids can be distinguished or the fluid quality can be monitored.

Resulting from incorrect use or from use other than that designated the operational safety of the measuring devices can be suspended. The manufacturer accepts no liability for damages being produced from this.

1.2Installation, commissioning and operation

Note the following points:

•Installation, connection to the electricity supply, commissioning and maintenance of the device must be carried out by trained, qualified specialists authorized to perform such work by the facility's owner-operator.

The specialist must have read and understood these Operating Instructions and must follow the instructions they contain.

•The device must be operated by persons authorized and trained by the facility's owner-operator. Strict compliance with the instructions in these Operating Instructions is mandatory.

•Endress+Hauser is willing to assist in clarifying the chemical resistance properties of parts wetted by special fluids, including fluids used for cleaning.

However, small changes in temperature, concentration or the degree of contamination in the process can result in changes to the corrosion resistance properties. Therefore, Endress+Hauser cannot guarantee or accept liability for the corrosion resistance properties of wetted materials in a specific application.

The user is responsible for choosing suitable wetted materials in the process.

•If carrying out welding work on the piping, the welding unit may not be grounded by means of the measuring device.

•The installer must ensure that the measuring system is correctly wired in accordance with the wiring diagrams. The transmitter must be grounded, except in cases where special protective measures have been taken (e.g. galvanically isolated power supply SELV or PELV).

•Invariably, local regulations governing the opening and repair of electrical devices apply.

1.3Operational safety

Note the following points:

•Measuring systems for use in hazardous environments are accompanied by separate "Ex documentation", which is an integral part of these Operating Instructions. Strict compliance with the installation instructions and ratings as stated in this supplementary documentation is mandatory. The symbol on the front of this supplementary Ex documentation indicates the approval and inspection authority (e.g. 0 Europe, 2 USA, 1 Canada).

•The measuring system complies with the general safety requirements in accordance with

EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR Recommendation NE 21 and NE 43.

•The manufacturer reserves the right to modify technical data without prior notice. Your Endress+Hauser distributor will supply you with current information and updates to this Operating Instructions.

1.4Return

The following procedures must be carried out before a flowmeter requiring repair or calibration, for example, is returned to Endress+Hauser:

•Always enclose a duly completed "Declaration of Contamination" form. Only then can Endress+Hauser transport, examine and repair a returned device.

! Note!

You will find a preprinted "Declaration of Contamination" form at the back of this manual.

•Enclose special handling instructions if necessary, for example a safety data sheet as per Regulation (EC) No 1907/2006 REACH.

•Remove all residues. Pay special attention to the grooves for seals and crevices which could contain residues. This is particularly important if the substance is hazardous to health, e.g. flammable, toxic, caustic, carcinogenic, etc.

#Warning!• Do not return a measuring device if you are not absolutely certain that all traces of hazardous substances have been removed, e.g. substances which have penetrated crevices or diffused through plastic.

•Costs incurred for waste disposal or injury (burns, etc.) due to inadequate cleaning will be charged to the owner-operator.

1.5Notes on safety conventions and icons

The devices are designed and tested to meet state-of-the-art safety requirements, and have left the factory in a condition in which they are safe to operate. The devices comply with the applicable standards and regulations in accordance with EN 61010 -1 "Protection Measures for Electrical Equipment for Measurement, Control, Regulation and Laboratory Procedures". The devices can, however, be a source of danger if used incorrectly or for other than the designated use.

For this reason, always pay particular attention to the safety instructions indicated in these Operating Instructions by the following icons:

#Warning!"Warning" indicates an action or procedure which, if not performed correctly, can result in personal injury or a safety hazard. Comply strictly with the instructions and proceed with care.

"Caution!"Caution" indicates an action or procedure which, if not performed correctly, can result in incorrect operation or destruction of the device. Comply strictly with the instructions.

!Note!"Note" indicates an action or procedure which, if not performed correctly, can have an indirect effect on operation or trigger an unexpected response on the part of the device.

3.1Incoming acceptance, transport and storage

3.1.1Incoming acceptance

On receipt of the goods, check the following points:

•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.

3.1.2Transport

The devices must be transported in the container supplied when transporting them to the measuring point.

3.1.3Storage

•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 ambient temperature range of the transmitter, the sensors and the corresponding sensor cables ( ä 119).

•The measuring device must be protected against direct sunlight during storage in order to avoid unacceptably high surface temperatures.

3.2Installation conditions

3.2.1Dimensions

The dimensions and lengths of the sensor and transmitter are provided in the separate "Technical

Information" document on the device in question. This can be downloaded as a PDF file from

www.endress.com.

A list of the "Technical Information" documents available is provided on ä 130.

3.2.2Mounting location

Correct flow measurement is possible only if a pipe is full. Entrained air or gas bubbles forming in the pipe can result in an increase in measuring errors.

Avoid the following locations in the pipe installation:

•Highest point of a pipeline. Risk of air accumulating.

•Directly upstream of a free pipe outlet in a vertical pipeline.

3.2.3Orientation

Vertical orientation

We recommend the sensor be mounted where there is upward direction of flow. With this orientation, entrained solids will sink down and gases will rise away from the sensor when the fluid is stagnant.

Horizontal orientation

We recommend the sensors be mounted within an angle of ±60° to the horizontal (area shaded gray in the graphic). With this orientation, flow measurement is less affected by any gas or air accumulation in the upper area of the pipe or by buildup at the bottom of the pipe.

3.2.4Inlet and outlet run

If possible, install the sensor well clear of assemblies such as valves, T-pieces, elbows, etc. If several flow obstructions are installed, the longest inlet or outlet run must be considered. Compliance with the following inlet and outlet runs is required in order to ensure measuring accuracy.

3.2.5Sensor selection and arrangement

The sensors can be arranged in two ways:

•Mounting arrangement for measurement via one traverse: the sensors are located on opposite sides of the pipe.

•Mounting arrangement for measurement via two traverses: the sensors are located on the same side of the pipe.

A B

A0001108

Fig. 7: Sensor mounting arrangement (top view)

AMounting arrangement for measurement via one traverse

BMounting arrangement for measurement via two traverses

The number of traverses required depends on the sensor type, the nominal diameter and the thickness of the pipe wall. We recommend the following types of mounting:

	Sensor Type	Nominal Diameter	Sensor Frequency		Sensor ID	Type of Mounting 1)
		DN 15 to 65 (½ to 2½")	6	MHz	P-CL-6F*	2 traverses 5)
		DN 50 to 65 (2 to 2½")	2	MHz	P-CL-6F*	2 (or 1) traverses
					P-CL-2F*
		DN 80 (3")	2 MHz		P-CL-2F*	2 traverses
	Prosonic Flow P
		DN 100 to 300 (4 to 12")	2	MHz (or 1 MHz)	P-CL-2F*	2 traverses
					P-CL-1F*
		DN 300 to 600 (12 to 24")	1	MHz (or 2 MHz)	P-CL-1F*	2 traverses
					P-CL-2F*
		DN 650 to 4000 (26 to 160")	1	MHz	P-CL-1F*	1 traverse
		DN 15 to 65 (½ to 2½")	6	MHz	W-CL-6F*	2 traverses 5)
		DN 50 to 65 (2 to 2½")	2	MHz	W-CL-2F*	2 (or 1) traverses 2)
		DN 80 (3")	2 MHz		W-CL-2F*	2 traverses
	Prosonic Flow W	DN 100 to 300 (4 to 12")	2	MHz (or 1 MHz)	W-CL-2F*	2 traverses 3)
					W-CL-1F*
		DN 300 to 600 (12 to 24")	1	MHz (or 2 MHz)	W-CL-1F*	2 traverses 3)
					W-CL-2F*
		DN 650 to 4000 (26 to 160")	1	MHz (or 0.5 MHz)	W-CL-1F*	1 traverse 3)
					W-CL-05F*

1)The installation of clamp-on sensors is principally recommended in the 2 traverse type installation. This type of installation allows the easiest and most comfortable type of mounting and means that a system can also be mounted even if the pipe can only be accessed from one side. However, in certain applications a 1 traverse installation may be preferred. These include:

•Certain plastic pipes with wall thickness > 4 mm (0.16")

•Pipes made of composite materials such as GRP

•Lined pipes

•Applications with fluids with high acoustic damping

2)If the pipe nominal diameter is small (DN 65 / 2½" and smaller), the sensor spacing with Prosonic Flow W can be too small for two traverse installation. In this case, the 1 traverse type of installation must be used.

3)0.5 MHz sensors are also recommended for applications with composite material pipes such as GRP and may be recommended for certain lined pipes, pipes with wall thickness > 10 mm (0.4"), or applications with media with high acoustic damping. In addition, for these applications we principally recommend mounting the W sensors in

a 1 traverse configuration.

4)Insertion W sensors are mounted in a 1 traverse configuration ä 45.

5)6 MHz sensors for applications where flow velocity 10m/s (32.8Hz/s)

3.3Two-channel operation

The transmitter is able to operate two independent measuring channels (measuring channel 1 and measuring channel 2). A pair of sensors is connected per measuring channel. Both measuring channels operate independently of one another and are supported by the transmitter to an equal extent.

Two-channel operation can be used for the following measurements:

•Two-channel measurement = flow measurement at two separate measuring points

•Two-path measurement = redundant flow measurement at one measuring point

3.3.1Two-channel measurement

The flow is measured at two separate measuring points in the case of two-channel measurement.

The measured values of the two measuring channels can be processed and displayed differently.

The following measured values can be output for two-channel measurement:

•Individual measured values per measuring channel (output independently of one another)

•The difference between the two measured values

•The sum of the two measured values

The two measuring channels can be configured individually. This makes it possible to independently configure and select the display, outputs, sensor type and type of installation.

3.3.2Two-path measurement

The flow is measured redundantly at one measuring point in the case of two-path measurement.

The measured values of the two measuring channels can be processed and displayed differently. The following measured values can be output for two-path measurement:

•Individual measured values per measuring channel (output independently of one another)

•The average of the two measured values.

The "Averaging" function generally provides you with a more stable measured value. The function is thus suitable for measurements under conditions that are not ideal (e.g. short inlet runs).

The two measuring channels can be configured individually. This makes it possible to independently configure and select the display, outputs, sensor type and type of installation.

It is generally not necessary to individually configure the two measuring channels in the case of twopath measurement. However, in certain situations individual channel configuration can be used to balance out application-specific asymmetries.

3.4Preparatory steps prior to installation

Depending on the conditions specific to the measuring point (e.g. clamp-on, number of traverses, fluid, etc.), a number of preparatory steps have to be taken before actually installing the sensors:

1.Determination of the values for the necessary installation distances based on the conditions specific to the measuring point. A number of methods are available for determining the values:

–Local operation of the device

–FieldCare (operating program), connect a notebook to the transmitter

–Applicator (software), online on the Endress+Hauser Internet site

2.Mechanical preparation of the clamp-on retainers for the sensors:

–Premount the strapping bands (DN 50 to 200 / 2 to 8") or (DN 250 to 4000 / 10 to 160")

–Fix the welded bolts

3.5Determining the necessary installation distances

The installation distances that have to be maintained depend on:

•The type of sensor: P or W (DN 50 to 4000 / 2 to 160"), P or W (DN 15 to 65 / ½ to 2½")

•Type of mounting:

–Clamp-on with strapping band or welded bolt

–Insertion version, installation in the pipe

•Number of traverses or single-path/dual-path version

3.7Mechanical preparation

The way in which the sensors are secured differs on account of the pipe nominal diameter and the sensor type. Depending on the type of sensor, users also have the option of securing the sensors with strapping bands or screws such that they can be later removed, or permanently fixing the sensors in place with welded bolts or welded retainers.

Overview of possible ways to secure the various sensors:

3.7.1Mounting the sensor holder with U-shaped screws

For mounting on a pipe with a nominal diameter of DN 32 (1¼")

For sensors: Prosonic Flow 93W or P (DN 15 to 65 / ½ to 2½")

Procedure

1.Disconnect the sensor from the sensor holder.

2.Position the sensor holder on the pipe.

3.Put the U-shaped screws through the sensor holder and slightly lubricate the thread.

4.Screw nuts onto the U-shaped screws.

5.Set the holder to the exact position and tighten the nuts evenly.

# Warning!

Risk of damaging plastic or glass pipes if the nuts of the U-shaped screws are tightened too much! The use of a metal half-shell is recommended (on the opposite side of the sensor) when working with plastic or glass pipes.

!Note!The visible pipe surface "A" must be smooth to ensure good accustic contact.
