KATflow 170

Clamp-on transittime flowmeter

1 Introduction

1 Introduction

The KATflow 170 is a fixed installation ultrasonic flowmeter designed for use in hazardous areas employing clamp-on sensors for the measurement of liquids in full, enclosed pipes. Flow measurements can be undertaken without interruption of the process or interference with the integrity of the pipeline. The clamp-on sensors are attached to the outside of the pipes. The KATflow 170 uses ultrasonic signals for measurement of the flow, utilising the transit-time method. The sensors of type

K1Ex and K4Ex are equally suitable for use in hazardous areas. The KF170 flowmeter can only be used with ATEX or IECEx certified sensors.

Illustration 1: Clamp-on ultrasonic flowmeter principle

Measuring principle Ultrasonic signals are emitted by a transducer installed on a pipe and received by a second transducer. These signals are emitted alternately in the direction of flow and against it. Because the medium is flowing, the transit time of the sound signals propagating in the direction of flow is shorter than the transit time of the signal propagating against the direction of flow. The transit-time difference ΔT is measured and allows the determination of the average flow velocity along the path of acoustic propagation. A profile correction is then performed to obtain the average flow velocity over the cross-sectional area of the pipe, which is proportional to the volumetric flow rate.

Illustration 2: Transit-time measuring principle

2.1 Unpacking and storage

2.1.1 Unpacking

Care should be taken when opening the box containing the flowmeter, any markings or warnings shown on the packaging should be observed prior to opening. The following steps should then be taken:

Unpack the flowmeter in a dry area.

The flowmeter should be handled with care and not left in an area where it could be subject to physical shocks.

If using a knife to remove packaging care should be taken not to damage the flowmeter or cables.

The flowmeter package and contents should be checked against the delivery note supplied and any missing items reported immediately.

The flowmeter package and contents should be checked for signs of damage during transport and any problems reported immediately.

The vendor accepts no responsibility for damage or injury caused during the unpacking of the instrumentation supplied.

Excess packing materials should be either recycled or disposed of in a suitable way.

2.1.2 Storage

If storage is necessary, the flowmeter and sensors should be stored:

● in a secure location, away from water and harsh environmental conditions, in such a way as to avoid damage, small items should be kept together in the bags provided to avoid loss.

2.1.3 Identification of components

The following items are typically supplied (please refer to your delivery note for a detailed description):

2.2 Clamp-on sensor installation

The correct selection of the sensor location is crucial for achieving reliable measurements and high accuracy. Measurement must take place on a pipe in which sound can propagate (see Acoustic propagation) and in which a rotationally symmetrical flow profile is fully developed (see Straight pipe lengths).

12

KATflow 170 2 Installation

Acoustic propagation

Straight pipe lengths

The correct positioning of the transducers is an essential condition for error-free measurements. It ensures that the sound signal will be received under optimal conditions and evaluated correctly. Because of the variety of applications and the different factors influencing the measurement, there can be no standard solution for the positioning of the transducers.

The correct position of the transducers will be influenced by the following factors:

● diameter, material, lining, wall thickness and general condition of the pipe, the medium flowing in the pipe, the presence of gas bubbles and solid particles in the medium.

Check that the temperature at the selected location is within the operating temperature range of the transducers (see Specification).

After the sensor location has been selected, make sure that that supplied cable is long enough to reach the flow transmitter mounting location. Ensure that the temperature at the selected location is within the ambient operating temperature range of the flow transmitter (see Specification).

Acoustic propagation is achieved when the flowmeter is able to receive sufficient signal from the transmitted ultrasonic pulses. The signals are attenuated in the pipe material, the medium and at each of the interfaces and reflections. External and internal pipe corrosion, solid particles and gas content in the medium contribute heavily to signal attenuation.

Sufficient straight lengths of pipe on the inlet and outlet of the measuring location ensure an axi-symmetrical flow profile in the pipe, which is required for good measurement accuracy. If insufficient straight lengths of pipe are available for your application measurements are still obtainable, but the certainty of the measurement can be reduced.

+

2.3 Installation location

Select an installation location following the recommendations in Table 1 and try to avoid measuring

● in the vicinity of deformations and defects of the pipe, near welding seams, where deposits could be building up in the pipe.

For a horizontal pipe:

Select a location where the transducers can be mounted on the side of the pipe, so that the sound waves emitted by the transducers propagate horizontally in the pipe. In this way, the solid particles deposited on the bottom of the pipe and the gas pockets developing at the top will not influence the propagation of the signal.

2.4 Pipe preparation

Clean dirt and dust from around the area of the pipework where the sensors are to be placed.

Remove loose paint and rust with a wire brush or file.

Firmly bonded paint does not necessarily need to be removed provided the flowmeter diagnostics indicate sufficient signal strength.

2.5 Clamp-on sensor mounting configurations and separation distance

The most common clamp-on sensor mounting configuration is the Reflection Mode, sometimes known as V-Mode (see Illustration 3, sketch (1). Here, the ultrasonic signal passes twice through the medium (2 signal passes). The Reflection Mode is the most convenient mounting method as the transducer separation distance can be measured easily and the sensors can be accurately aligned. This method should be used whenever possible.

An alternative mounting configuration (Illustration 3, sketch (3)) is the Diagonal mode (Z-Mode). The signals travel only once through the pipe. This method is often used for larger pipes where greater signal attenuation might occur.

Further variation of the Reflection and the Diagonal Modes are possible by altering the number of passes through the pipe. Any even number of passes will require mounting the sensors on the same side of the pipe, while with an odd number of passes, the sensors must be mounted on opposite sides of the pipe. Commonly, for very small pipes, sensor mounting configurations such as 4 passes (W-mode) or 3 passes (N-mode) are used (Illustration 3, sketch (2)).

Transducer separation distance

Sensor spacing

+

Illustration 5: Clamp-on sensor mounting configurations and sensor spacing

The transducer separation distance A is measured from the inside edges of the sensor heads as shown in illustration 3. It is automatically calculated by the flowmeter based on the parameter entries for pipe outside diameter, wall thickness, lining material and thickness, medium, process temperature, the sensor type and the selected number of signal passes.

A negative separation distance A < 0 can occur for mounting configurations on small pipes where diagonal mode operation has been selected (see Illustration 3, sketch (3). Negative separation distances may be suggested for reflection mode installations, but are not possible. In these cases, use diagonal mode or a larger number of passes.

3.1 Cabling and junction box

The hazardous area K1Ex and K4Ex sensors are manufactured with a standard cable length of 5 m. If this cable length is sufficient for the application, then the sensors can be connected directly to the flowmeter (direct cable connection).

For installations requiring longer cable lengths, the sensors are terminated at an Ex e (increased safety) certified junction box with approved terminals.

The electrical connection between the junction box and the flowmeter (signal cabling) is established using type KAT01 dual coax cable. The cable ends of the coaxial cables must be appropriately terminated with tinned ends or suitably sized ferrules. The signal cable is provided with the system. The maximum recommended signal cable length is 100 m.

DANGER

Where the connecting sensor and/or signal cable may be subject to mechanical damage then the user shall provide additional mechanical protection.

3.1.1 Signal cable parameters

The signal cable supplied with the instrument has the following parameters:

Total attenuation 0.021 dB/m

Capacitance (core/screen) 107 pF/m

Inductance (core/screen) 0.24 μH/m

3.2 Cable glands

The KF170 housing features 2 x M20 cable entries for the sensor cabling and 4 x

M20 cable entries for power supply, communication and process input/output connections.

The KF170 housing is supplied with plastic dust caps. The temporary plugs are only intended for sealing the equipment against entry of dust, moisture or other possible ingress during transport, handling and storage. These dust caps must be replaced by suitable Ex e approved cable glands, stopping plugs or conduit adapters with respective sealing before the flowmeter is put into operation.

The installer is responsible for the correct sizing and selection of the Ex e approved cable glands for the explosion-proof box. Unused cable entries must be closed with suitable Ex e blind plugs. Ex e approved cable glands/blind plugs are not part of the standard delivery package and must be provided by the customer or explicitly ordered from KATRONIC.

Before the sensors can be mounted

● the installation location should have been determined, a sensor mounting method should be chosen, the flowmeter must be mechanically and electrically installed, the sensors must be connected to the flowmeter.

Depending on which sensor mounting method is being used, the clamp on sensors are either mounted on the same side of the pipe (Reflection Mode) or on opposite sides of the pipe (Diagonal Mode). The sensor spacing is calculated by the flowmeter from the pipe parameters entered.

3.5.2 Acoustic coupling gel

In order to obtain acoustical contact between the pipe and the sensors, apply a bead of acoustic coupling gel lengthwise down the centre of the contact area of the sensors.

Correct sensor position

3.5.3 Correct positioning of the sensors

Illustration 10: Application of acoustic coupling gel

+

Illustration 11: Correct positioning of the sensors

Always mount the transducer pair so that the free front edges of the sensors face each other.

There is a different engraving on the top of each transducer. The transducers are mounted correctly if the engravings on the two transducers form an arrow. The transducer cables should point in opposite directions.

Later, the arrow, in conjunction with the indicated measured value, will help to determine the direction of flow.

The sensor separation distance is automatically calculated by the flowmeter based on the parameter entries for pipe outside diameter, wall thickness, lining material and thickness, medium, process temperature, the sensor type and the selected number of signal passes.

3.5.4 Sensor mounting with tension straps

3 Electrical installation

Illustration 12: Metallic mounting straps

Cut the tension straps to the appropriate length.

Pull at least 2 cm of the tension strap through the slot in the clamp and bend the strap back to secure the clamp to the tension strap.

Guide the other end of the tension strap through the groove on top of the sensor.

Place the sensor onto the prepared pipe section.

Hold the clamp on the transducer with one hand and guide the tension strap around the pipe.

Pull the tension strap and guide the free end through the clamp so that the clamp hooks engage. Slightly tighten the screw on the clamp.

Mount the second sensor in the same way.

Press the sensors firmly to the pipe. There should be no air pockets between the transducer surface and the pipe wall.

Using a measuring tape, adjust the sensor separation distance as suggested by the flowmeter. When the sensor positioning screen is displayed, the middle bar allows fine adjustment of the sensor location.

Table 6: Error messages

7.1 Data download difficulties

If difficulties are encountered downloading the logger data : -

● Check that the flowmeter is switched on and not in measurement mode.

Check that the same number COM port is allocated in the “Device

Manager” (or equivalent) as is set in the KatData+ software.

Check that the settings (baud, parity, word length, stop bits) are identical.

Use the supplied connectors – whether connecting to a 9-pin COM port or converting from serial communication to a Universal Serial Bus (USB).

Is the logger in "Wrap" mode? If "yes", use a terminal program and the

"Log download" command. If "No", KatData+ software may also be used.

Frequently Answers and Questions

What is the maximum recommended signal cable length for the KATflow 170?
The maximum recommended signal cable length is 100 m.
What are the temperature limits for the KATflow 170 transmitter?
For KF170 flowmeters located in Zone 1 or 2 hazardous areas the ambient temperature range is -20 ... 60 °C.
Where should the transducers be mounted on the pipe for optimal acoustic propagation?
Select a location where the transducers can be mounted on the side of the pipe, so that the sound waves emitted by the transducers propagate horizontally in the pipe.
What are the types of clamp-on sensor mounting configurations available?
The most common configuration is the Reflection Mode, sometimes known as V-Mode. An alternative is the Diagonal mode (Z-Mode).
What is the purpose of the acoustic coupling gel?
To obtain acoustical contact between the pipe and the sensors, apply a bead of acoustic coupling gel lengthwise down the centre of the contact area of the sensors.
How do I determine the correct positioning of the sensors?
Always mount the transducer pair so that the free front edges of the sensors face each other. The transducers are mounted correctly if the engravings on the two transducers form an arrow.
