5.4 Flowcell Problems

If preliminary troubleshooting using the

Error Codes

in Chapter 4 and

“Displaying Diagnostic Parameters” on

page xcv

indicates a possible flowcell problem, proceed with this section.

Flowcell problems fall into two general categories:

• Gas problems
• Pipe problems.

Read the following sections carefully to determine if the problem is indeed related to the flowcell. If the instructions in

this section fail to resolve the problem, contact Panametrics for assistance.

5.4.1 Gas Problems

Most gas-related problems result from a failure to observe the

Sentinel Flow Measurement System

installation

instructions. Refer to Chapter 1,

Installation

, to correct any installation problems.

If the physical installation of the system meets the recommended specifications, it is possible that the gas itself may

be preventing accurate flow rate measurements. The gas being measured must meet the following requirements:

•

The gas must be homogeneous, single-phase and relatively clean.

Although a low level of entrained particles may have little effect on the operation of the

Sentinel

system,

excessive amounts of solid (smoke) or liquid (steam) particles will absorb or disperse the ultrasound signals.

This interference with the ultrasound transmissions through the gas will cause inaccurate flow rate

measurements. In addition, temperature gradients in the gas flow may result in erratic or inaccurate flow rate

readings.

•

The gas must not excessively attenuate ultrasound signals.

Some gases (e.g., high-purity carbon dioxide, hydrogen, nitrogen, etc.) readily absorb ultrasound energy. In

such cases, an

error code message will appear on the meter display screen to indicate that the ultrasonic

signal strength is insufficient for reliable measurements.

•

The gas soundspeed must not vary excessively.

The Sentinel system will tolerate relatively large changes in the gas soundspeed, as may be caused by

variations in gas composition or temperature. However, such changes must occur slowly. Rapid fluctuations in

the gas soundspeed, to a value that is considerably different from that programmed into the

Sentinel

, will result

in erratic or inaccurate flow rate readings. Refer to

“Displaying Measurements” on page lxxix

, and make sure

that the appropriate soundspeed appears in the soundspeed display.
