Sonaray Configuration

SlipMeter Site Summary component > FlowMeter Status > Configuration

The Sonaray Configuration screen displays some calibration, status and configuration settings related to the Sonaray Meter.

Note

Configuration settings for the Sonaray meter are password protected. The meter must be in Configuration Mode before any configuration changes can be made.

To place the meter in configuration mode:

  1. In the Flowmeter Status screen, click the Configuration button to open the Configuration screen
  2. Click the Configuration Password setter and enter the configuration password. This places the meter into Configuration mode for ten minutes.

    Note

    The Configuration Password setter always displays 0, not the actual password.

Circuit Serial Number Serial number of the SlipMeter electronics. ISR_CIRCUIT_SERNO

Password Settings

Field Description Tag

Configuration Password

 Enter the configuration password to place the meter in Configuration mode for ten minutes

You can change this password in Configuration mode using the New Password setter.

ICONFIG_PWD_SP

Configuration User ID

User ID of the user who logged in to Configuration mode. This is stored for auditing purposes.

ICONFIG_USER_ID

Configuration Mode Enabled

Indicates whether the meter is currently in Configuration mode

CONF_MODE_ENABLED

New Password

Set the Configuration Password. The password can only be changed in Configuration mode.

INEW_PASSWORD_SP

Password Updated

Indicates whether the password was updated last time the meter was in Configuration mode.

PASSWORD_UPDATED
Date/Time These tags are used to display the time on the Sonaray. Use the Sync button to synchronise the time to the RTU. The hours are defined in 24 hour format. ITIME_X where X is the time field. i.e. DAY, MONTH, YEAR, HOUR, MINUTE and SECOND.

Calibration Settings

Field Description Tag
Minimum Flow Rate Minimum calibrated flow rate for the meter. IMIN_CALIB_FLOW_Q1
Maximum Flow Rate Maximum calibrated flow rate for the meter IMAX_CALIB_FLOW_Q2
Overload Flow Rate Overload flow rate of the meter. When the measured flow rate exceeds this value, the reading is considered to be invalid and will be ignored by the volume accumulator IOVERLOAD_FLOW_Q4

Sonaray Water Level Settings

Field Description Tag

Sonaray W/L Datum

Water level datum for the Sonaray water level

 SONARAY_WL_DATUM

Water Level Update

If this is enabled, the corrected water level is written to the Sonaray using the configured datum.

 ENABLE_WL_UPDATE

Ultrasonic Spacer Length

Length of the spacer tube used in the ultrasonic level sensor

 lULTRASONIC_SPACER_LENGTH_101

Communications Settings

Field Description Tag

Sonaray Modbus Address

Sonaray local communications MODBUS device address

ISONARAY_MDB_ADD

Communications Protocol

Communications protocol which may be either Modbus RTU or Modbus ASCII

ICOMM_PROTOCOL

Baud Rate

Baud rate for communication between the sonaray and the RTU. Defaults to 9600

IBAUD_RATE

Data Bits

Number of bits used for data transmission which may be between 5 and 8 (default)

IDATA_BITS

Parity

Specifies the parity type which may be even, odd or not used (default)

IPARITY

Stop Bits

Number of stop bits 1 (default), 2 or 1.5

ISTOP_BITS

Gate Closed Configuration

Field Description Tag
Gate Closed Feature Indicates whether the Gate Closed feature is enabled.

If the feature is enabled, the processed flow rate is set to zero when the gate is closed and the flow accumulators are not updated

 GATE_CLOSED_CONFIG

Gate Closed DB

Gate position deadband. If the difference between the gate position and fully closed is within this threshold, the gate is considered closed.

 IGATE_CLOSED_POS

Flow Configuration

Field Description Tag

Low Flow Feature

Specifies whether the Low Flow feature is enabled. If this feature is enabled, then, when the flow is below the low flow cutoff value, the processed flow rate is set to zero and the accumulators are not updated.

LOW_FLOW_CONFIG

Low Flow Cutoff

Flow rate where Low Flow behaviour is initiated.

ILOW_FLOW_CUTOFF

Leakage Volume Threshold

Threshold amount of leakage permitted from a closed valve. If the leakage detected over the Leakage Volume Period exceeds this threshold, the Leakage Alarm is triggered.

ILEAK_VOL_THRESH

Leakage Volume Period

Time in seconds over which the leakage volume is monitored.

ILEAK_SAMP_TIME

Modify Accumulator

Current accumulator value

IFLOW_NET_ACU_FILTER

Modify Accumulator Setpoint

Reset or adjust the volumetric accumulator values. To reset the accumulators, write a tag setpoint value of zero. To set the accumulators to another value, write the required value as the tag setpoint. The Net Volume and Forward Volume accumulator values (both raw and processed) will be set to the value entered and the Reverse Volume (both raw and processed) will be set to zero. The accumulators will then continue accumulating past this point.

IMODIFY_ACU_SP

Filter Coefficient

A calculation coefficient used in the flow calculations.

IFILTER_COEF

Maximum Flow Rate Threshold

Flow rate above which the MAX_FLOW_EXCEEDED alarm will be set. Set the Maximum Flow Rate Threshold to zero to disable this alarm functionality.

IMAX_FLOW_RATE

Path Velocity Maximum Limit

Maximum expected velocity limit. Measurements above this limit are capped to this value.

 lVELOCITY_MAX

Path Velocity Filter Coef.

Coefficient used in path velocity calculations

 iVELOCITY_FILTER_COEFFICIENT

Path Exclusion Enabled

Specifies whether the Path Exclusion feature is enabled. If the feature is enabled, paths are excluded from flow calculations if they are not measuring accurately.

 PATH_EXCLUSION_EN

Silt Flushing Configuration

Field Description Tag

Silt AutoFlush Trigger

 Configure the silt autoflush trigger.

Use the setpoint to set the number of silt-affected planes that will trigger a flush action, or set to DISABLED to disable silt flushing.

For example, set to 2 to initiate flushing when two or more planes are blocked by silt.

 SILT_CHK_PLANE_COUNT

Silt Flush Position Setpoint

Set the gate position to use while flushing.

 SILT_FLUSH_POS_SP
