Diagnostic Screens

Evaluating and Controlling the Diagnostics Screen

The diagnostic data screen presents a significant amount of valuable data for the

purpose of both monitoring and evaluating system performance. The data presented,

their descriptions and their expected values are outlined below.

Process Values

Flow Rate: Presents the actual (Gross) volumetric flow rate in the measurement units

selected in the Flowmeter program

Standard Volume Flow Rate: Presents the volumetric flow rate compensated for pressure,

temperature and where applicable; compressibility factor. Only certain versions of the

FS230 flowmeter can produce Standard volume flow data. The volumetric units are as

selected in the Flowmeter program.

Path Diagnostics

RX Gain (Up – Dn): These values indicate the signal strength of the flow sensor

(transducer) signal and differentiate between the upstream traveling and downstream

traveling signals. The data is presented in Db with lower values being better. The default

warning limit is any value above 40 while the fail limit is a value above 50.

SNR (Up – Dn): These values indicate the signal to noise ratio of the flow sensor

(transducer) signal and differentiate between the upstream traveling and downstream

traveling signals. The data is presented in Db with higher values being better. The default

warning limit is any value below 20 while the fail limit is a value below 10.

Status: Indicates the operating condition of the flowmeter. When application conditions are

acceptable; and all diagnostic parameters are meeting minimum requirements, the status

will indicate “Measurement”. If conditions cause an operating parameter to be

unsuitable; interruption of flow measurement may occur. In such cases the status will

change to indicate the underlying issue

Correlation Q: This value is derived from a signal (phase) analysis by comparing the phase

differential of the initial receive signal frequency cycle to that of a later occurring cycle of

the same signal. When the two match perfectly the “Cor-Q” is 1.0. The default value at

which a warning is generated is below 0.95, a Fail is declared if the value is below 0.92

In gas systems where very large signal phase shifts can occur, the Cor-Q can be

improved by performing an “HF” adjustment in the flowmeter “Maintenance and

Diagnostics” menu

% Accepted: This parameter indicates the percentage of acoustic signal

transmissions/receives that are used for flow measurement with the ideal value being

100%. If application conditions such as high aeration or noise interference are present,

some of the receive signals will be unacceptable and rejected by the flowmeter. In these

cases, the [% accepted] will decrease. The default warning limit is less than 50%

accepted while the Fail limit is less than 20%.

Delta-Time usec: Indicates the displacement (Phase shift) between the upstream vs

downstream flow signal and is indicated in microseconds. This differential is caused by

the flow velocity acting upon the flow sensor signal propagation through the flow stream.

Flow & Vos

Flow Velocity: Indicates the speed of flow through the pipe in the velocity units selected in

the Flowmeter program

VoS: Indicates the velocity of sound propagation through the flow medium. The units are in

the sound velocity units selected in the flowmeter program
