Chapter 1. General Information

1.1 Theory of Operation

The PanaFlow Z1G/Z2G Process Gas Flowmeter system uses ultrasonic transit-time technology. A brief description of transit-time theory follows. For more information about the theory, and the use of BHGE ultrasonic flow meters for measuring flow, please refer to Ultrasonic Measurements for Process Control by L.C. Lynnworth (Academic Press, 1989).

1.1.1 Transit-Time Method

The transit time technique uses a pair of transducers, with each transducer alternately sending and receiving coded ultrasonic signals through the fluid. When the fluid is flowing, signal transit time in the downstream direction is shorter than in the upstream direction. The difference between these transit times is proportional to the flow velocity. The PanaFlow Z1G/Z2G Process Gas Flowmeter measures this very small time difference and, using various digital signal processing techniques combined with programmed pipe parameters, determines the flow rate and direction.

1.1.2 Transducers

When in a transmit cycle, transducers convert electrical energy into ultrasonic pulses and then convert the ultrasonic pulses back to electrical energy when in a receive cycle. In other words, they act like loudspeakers when transmitting the signal and like microphones when receiving it. They perform the actual data transmission and collection, thus interrogating the flow.

1.2 Multi-Path Design

Multi-path ultrasonic flow meters are designed to accommodate more than one pair of transducers to interrogate the flow field in different locations and more accurately determine the actual flow rate. The PanaFlow Z1G/Z2G Process Gas Flowmeter system is available in either a 1-Path or 2-Path configuration. For the 2-Path configuration, the measurement paths are located either at Diametrical path or at Midradius configurations. In addition to the flow transducers, the PanaFlow Z1G/Z2G Process Gas Flowmeter can be fitted with optional temperature and pressure transducers to permit mass flow measurements.

1.3 Flow Profile

One of the main factors affecting an ultrasonic flow measurement is the flow profile. If the flow profile is known, mathematical modeling of the flow and the relationships between the raw data of the two paths can be made. Maintaining a constant flow-profile shape across all flow velocities, pipe sizes and upstream flow disturbances can be difficult. For this reason, BHGE has tested the PanaFlow Z1G/Z2G Process Gas Flowmeter under various conditions in an effort to determine its operational limits.

Chapter 1. General Information

1.4 Unpacking

The PanaFlow Z1G/Z2G Process Gas Flowmeter is typically packaged in a wooden crate, the size of which will depend on the size of product ordered. The flowcell is secured by several 2x4 wood blocks to prevent shifting during transit. Simply remove these 2x4 braces to unpack the system. For local-mount systems the transmitter electronics enclosure is installed directly on top of the flowcell via an adapter. For remote-mount systems the transmitter electronics enclosure and the remote cable may ship in a separate package.

1.5 Inspection

Prior to installation, inspect all materials to be used in the installation:

• Gaskets - check for cracks, tears and over compression

• Nuts and Bolts - check for damaged threads and for debris

• RF Flange Faces - check for damage to serrations that may cause gaskets to not seal properly.

In general, check for anything that may prevent safe operation of the equipment.

IMPORTANT: If pipes are shipped pre-assembled as a single section, care should be taken to inspect and check

the bolts and gaskets.

2.1 Introduction

To ensure safe and reliable operation of the PanaFlow Z1G/Z2G Process Gas Flowmeter, the system must be installed in accordance with the guidelines established by BHGE engineers. Those guidelines are explained in detail in this chapter.

WARNING! The PanaFlow Z1G/Z2G Process Gas Flowmeter can measure the flow rate of many gases, some of which are potentially hazardous. In such cases, the importance of proper safety practices cannot be overemphasized.

Be sure to follow all applicable local safety codes and regulations for installing electrical equipment and working with hazardous gases or flow conditions. Consult company safety personnel or local safety authorities to verify the safety of any procedure or practice.

Attention! To meet CE Mark requirements for all units intended for use in the EU or in high electrical noise environments, all electrical cables must be installed as described in Appendix A, “CE Mark Compliance and High Noise Environments”.

2.2 Lifting Instructions

Use proper lifting techniques when moving the PanaFlow Z1G/Z2G Process Gas Flowmeter. No lifting hooks or eyelets are provided. The recommended method for lifting the PanaFlow Z1G/Z2G Process Gas Flowmeter is by using lifting straps on each side of the spool with a stabilizer bar between them, located above the transmitter head. Additional care may need to be taken to prevent the transmitter from rotating, especially on the smaller systems where the transmitter weight is a larger percentage of the total system weight. A label similar to Figure 6 below, which illustrates these required precautions, is attached to the flowcell.

2.3 Flowcell Location Guidelines

The flowcell includes the flow transducers and, optionally, pressure and temperature transmitters. Ideally, install the flowcell in a section of pipe with access to the flowcell, such as a long run of pipe that is above ground. Observe the following recommendations:

• There should be at least 20 pipe diameters of straight, undisturbed flow upstream and 10 pipe

diameters of straight, undisturbed flow downstream from the measurement point. To ensure undisturbed flow, avoid sources of disturbances in the fluid such as valves, flanges, expansions, and elbows.

• Because condensate or sediment at the bottom of the pipe may cause attenuation of the ultrasonic

signal, always install the PanaFlow Z1G/Z2G Process Gas Flowmeter with the transmitter in a vertical orientation on the top of the pipe. This ensures that the transducers are located on the sides of the pipe rather than on the top or bottom.

• Only authorized personnel should perform the installation. The proper personal protection

equipment (PPE) should always be used when working with this equipment.

• The flowcell shall be installed in such a way that it can be safely operated, maintained and inspected.

Please refer to specific outline and installation drawings for proper clearances and specific distances for each system size. In general, allow for a minimum of 12” of space on all sides of the flowcell and flow transmitter, with an ideal clearance of 24” on all sides.

• You must provide suitable over-pressure protection at the main piping to the flowcell in order to

prevent damage to the flowcell and injury to personnel. The utilized over-pressure protection device shall be supplied with all declarations of conformity and EC-type design certificates.

PanaFlow™ Z1G/Z2G User’s Manual 9

Chapter 2. Installation

• Make sure the difference between the inside diameter of the pipe and that of the PanaFlow Z1G/Z2G

Process Gas Flowmeter does not exceed 0.5%, as changes in internal diameters will cause flow profile

disturbances.

• Make sure any non-symmetrical offset does not exceed 1%, as misalignment between the piping and

the meter may cause flow profile disturbances.

• Make sure the gasket is centered on the flange faces and does not protrude into the pipe, as

protrusion of the gasket into the pipe may cause flow profile disturbances.

• If pipe insulation is required, install all insulation materials and accessories in accordance with the

manufacturer's instructions and recognized industry practices. Adhere to the local code where applicable to ensure that the safe and proper installation will serve its intended purpose.

2.4 Making the Electrical Connections

This section contains instructions for making all the necessary electrical connections to the PanaFlow Z1G/Z2G Process Gas Flowmeter. Refer to Figure 13 on page 19 for a complete wiring diagram.

Note: Except for the power connector, all electrical connectors are stored on their terminal blocks during

shipment and may be removed from the enclosure for more convenient wiring. Simply, feed the cables through the conduit holes on the side of the enclosure, attach the wires to the appropriate connectors, and plug the connectors back into their terminal blocks.

To prepare the PanaFlow Z1G/Z2G Process Gas Flowmeter for wiring, refer to Figure 9 below, and complete the following steps:

counterclockwise until it comes free from the enclosure.

4. Install any required cable clamps in the appropriate conduit holes around the side of the enclosure.

5. Refer to the labels inside the rear cover to assist in making the power and option card connections.

Also, Figure 14 on page 20 shows the specific connection labels for all available option cards.

2.4.1 Wiring the Line Power

The PanaFlow Z1G/Z2G Process Gas Flowmeter may be ordered for operation with power inputs of either 85-240 VAC (standard) or 12-28 VDC (optional). The tag plate on the side of the electronics enclosure lists the required line voltage and the power rating. Be sure to connect the meter only to the specified line voltage.

WARNING! Proper grounding of the PanaFlow Z1G/Z2G Process Gas Flowmeter is required to prevent the possibility of electric shock. See Figure 11 on page 17 for the location of the chassis grounding screw.

WARNING! For compliance with the European Union’s Low Voltage Directive, this unit requires an external power disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such, clearly visible, directly accessible, and located within 1.8 m (6 ft) of the meter.

WARNING! Improper connection of the line power leads or connecting the meter to the incorrect line voltage may damage the unit. It may also result in hazardous voltages at the flowcell and associated piping as well as within the electronics enclosure.

Refer to Figure 13 on page 19 to locate the correct terminal block, and connect the line power as follows:

1. Prepare the line power leads by trimming the line and neutral AC power leads (or the positive and negative DC power leads) to a length 0.5 in. (1 cm) shorter than the ground lead. This ensures that the ground lead is the last to detach if the power cable is forcibly disconnected from the meter.

2. Install a cable clamp in the conduit hole closest to the power terminal block. Avoid using the other conduit holes for this purpose to minimize any interference in the circuitry from the AC power line.

3. Strip 1/4 in. of insulation from the end of each of the three power line leads.

4. Route the cable through the conduit hole and connect the line power leads to the terminal block,

using the pin number assignments shown in Figure 13 on page 19.

5. Leaving a bit of slack, secure the power line with the cable clamp.
