FlowMeter Status
SlipMeter Site Summary component > Flowmeter Status button
The FlowMeter Status screen displays flowmeter sensor details for SlipMeters and other products with flowmeters.
- FlowMeter Status
- Sonaray Configuration button
- Velocity Profile Diagnostics
The FlowMeter status screen includes the following sections:
FlowMeter Status
Alarm indicators are green to indicate normal opreation (OK status) and red to indicate a problem or error (FAIL status).
Details are given for the upstream sensor tags only. The downstream tags behave in the same way.
Field | Description | Tag |
---|---|---|
Sonaray Software Version | Sonaray software version number. | ISOFTWARE_VERSION |
Meter Interface Version | Meter interface software version number. | IFACE_VER_NO |
Flowmeter Comm Status | Status of the communications link between the RTU and the SONARAY MODBUS device (flow meter). |
FM_COMM_STATUS
|
Pipe Not Full | Indicates whether the pipe is not completely submerged.
The meter can detect this condition with its integrated ultrasonic level sensor, and amend the flow calculations accordingly, but there may be some loss of accuracy. |
PIPE_NOT_FULL
|
Low Flow | Indicates whether the flow is below the low flow cutoff value. Below this value the flow rate is not considered reliable and the flow accumulators are not updated. |
LOW_FLOW
|
Leakage Alarm | Indicates whether there is leakage at the meter when the gate is closed.
This is detected by checking the change of volume over a standard duration and comparing it to a specified tolerance. These settings are configured in the Leakage Volume parameters in the Flow Configuration section of the Flowmeter Status screen. |
LEAKAGE_ALARM
|
Insufficient Paths |
Indicates whether the meter has enough readings available to accurately measure the flow velocity profile. An insufficient paths condition may be caused by low water levels, tampering with the meter, weeds, or silt in the pipe. |
INSUFFICIENT_PATHS |
Silt Flush Status | Indicates that a silt flush is underway. Silt can be flushed automatically if the Sonaray is configured to do so. | SILT_FLUSH_STATUS |
Max Flow Exceeded | Flow has exceeded the maximum value for which the meter is calibrated. | MAX_FLOW_EXCEEDED |
No Water Level Sensor Replies | Indicates whether there have been any valid signals from any water level sensor within a specified timeout period. |
USWLS_COMMS_ERR
|
Flow Overload | Indicates whether flow has exceeded the overload flow rate (IOVERLOAD_FLOW_Q4). In this case, the calculated flow rate is considered invalid and is ignored by the flow accumulators. | FLOW_OVERLOAD |
Watchdog Reset |
Indicates whether the most recent reset of the meter was due to the watchdog timer. The watchdog timer is a safeguard that resets the meter if it has locked up or become unresponsive for a specified length of time. |
WATCHDOG_RST |
Accumulator Storage Full | Indicates whether the flowmeter has used all the available accumulator backup memory. | ACU_STORAGE_FULL |
Gate Position Status | Indicates if the gate is open or closed. The gate is considered to be closed when the current gate position (opening) is less than or equal to the gate closed deadband (IGATE_CLOSED_POS). Otherwise the gate is considered to be open. |
GATE_CLOSED
|
Gate Positioning (Opening) | Displays the current gate position when a gate (SlipGate) is connected to the Sonaray Meter. | IGATE_POSITION |
For the following fields, the Processed (filtered) value includes any corrections for Pipe not Pull, Gate Closed and Low Flow conditions while the Raw value does not. | ||
Current Flow | Raw and processed values of the instantaneous flow rate. | IFLOW_VAL IFLOW_VAL_FILTER |
Net Volume | Raw and processed values of the net volume measured. | IFLOW_NET_ACU IFLOW_NET_ACU_FILTER |
Forward Volume | Raw and processed values of the volume measured in the forward direction. | IFLOW_FOR_ACU IFLOW_FOR_ACU_FILTER |
Reverse Volume | Raw and processed values of the volume measured in the reverse direction. | IFLOW_REV_ACU IFLOW_REV_ACU_FILTER |
