Parameter Settings 8-23
value resulting from subtracting the reduced height from the default value of 0.394 in
(10 mm).
When using the air-ultrasonic sensor, enter the distance between the bottom edge of
the sensor and the pipe bottom.
The standard mounting height for the combi sensor with the pressure cell is 0.197 in
(5 mm), which represents the elevation of the sensor diaphragm above the pipe
bottom. It is not necessary to modify this value unless the sensor will be installed
higher or offset sideways. When installed higher, enter the total elevation of 0.197 in
(5 mm) plus the additional height.
Scale
This parameter is available only when sensor type 3 or 4 is selected.
To configure this parameter as a fixed value, enter the persistent water level. For a
full pipe, this value would be equivalent to the inside diameter of the pipe.
When using external sensors, enter the offset (to be added to the reading) and
measurement range (equivalent to 20mA of the FlowShark Pulse analog input).
Adjust the scale according to the measurement range or the scale of the
corresponding external depth sensor’s analog output.
Connection
This parameter is not available if the external depth sensor (sensor type 3, 8, or 10) is
selected. The user can enable the respective terminal clamp by clicking the ALT key.
Two-wire sensors must be connected to terminal clamps D8 and D9.
Select Ex-Zone from the Connection menu.
External level signals must always be connected to the non-Ex
area. Under this condition, select All from the Connection menu.
To connect these sensors, refer to Chapter 6, Installation.
Split Sensors
This parameter is available only when the unit is set up for combined depth
measurement (sensor combinations 6–12).
The user can choose up to 3 level zones: bottom, center, and top. Toggle among the
zones using the Alt key, and set the desired method for measuring depth for each
zone. The only methods available for selection are those that have been previously
selected during sensor type selection.
After selecting the method for measurement, set the height at which to switch the
FlowShark Pulse to the adjacent zone.
