Sick ultrasonic flow meter manual

It is overload-proof, accurate and monitored by an intelligent diagnostics system. Recalibration is simple and straightforward by replacing the cartridge. It complies with all relevant standards and regulations. Each of the ultrasonic gas flow meters in the FLOWSICXT product family has been designed for custody transfer applications and fulfills the requirements of all the common national and international standards.

There are four device versions to choose from to meet specific gas flow meter performance requirements. Dual pulse trains are provided simultaneously in both the forward and reverse flow directions for pulse fidelity and integrity checking. The phase shift in the forward direction is 90 degrees and degrees in the reverse direction.

It is possible to use this configuration with the OMNI flow computer if configuring two separate meter runs in the flow computer with each meter run representing different flow directions, and with each meter run assigned different flow pulse input channels.

Both signals are normally active simultaneously in either the forward or reverse flow directions. The signals are mutually exclusive of one another - while one signal is on, the other is off.

The DO1 signal is used to indicate forward flow and the DO0 signal is used to indicate reverse flow. The flowmeter response time can vary depending on the tasks being performed at the time data is requested. If the specified number of retries has been exhausted without a response from the flowmeter, the flow computer will raise a communications failure alarm. Assign flowmeter pulse signals only to Input Channels 3 and 4 of A or E combo modules, or input channel 3 of a B combo module.

Ensure the pulse train signals are wired accordingly. Set up the flow computer to totalize either the forward or the reverse flow on any meter run with an ultrasonic flowmeter. This input signal is used for purposes of flow pulses totalizing only and not for totalizing with respect to the serial port data. The OMNI will use this status signal if there is a failover from the serial communications link to the pulses OR if the pulses are specified as the primary means of measurement.

Specify which digital input channel in the OMNI will be receiving the signal indicative of the measurement status. This means that the SV serial communications data will be the primary and the pulse input channel, if assigned, will be used as a backup means of flow calculations by the flow computer.

This means that the flow pulses received from the flowmeter will be the primary and the SV serial communications data will be used as a backup means of flow calculations by the flow computer. The flow computer will raise an alarm if this percentage limit is exceeded.

The time interval can be set for comparing the flow pulses input flow with the SV communications serial link flow. If the flow deviation exceeds the Flow Deviation Percent setting see next setting when this comparison is made, the OMNI will switch from the primary flow pulses to the backup source SV serial link for calculating flow. NOTE: It is recommended a minimum of 60 minutes be specified for this setting due to the fluctuating flow pulse frequency.

The OMNI raises the pulse suspect alarm if the flow deviation percentage exceeds this limit and switches to the SV serial port as the primary means of totalizing. Depending upon how much time the communication link and pulses were inoperative and the amount of flow that occurred during this downtime, when communications is reestablished within the time specified in this setting, the OMNI may have to add a significant amount of flow to its totalizers.

These tables categorize data type. The OMNI raises an alarm if this percentage limit is exceeded. VolErr xxxx. This support greatly simplifies the work of the measurement engineer when identifying and solving faults in the gas flow meter and in the system as well. Changes to diagnostic data of the meter can often be traced back to changes in the process and the system.

He has been working in various positions in the area of solutions for flow measurement. Improving gas flow measurement with integrative diagnosis Changes to the system status are quickly detected, for example as a result of contamination, moisture in the gas or disruptive noises.
