how to set calibration range in a DP transmitter to measure
level for a closed tank and for an open tank,and also please
explain me how to set calibration range for a DP flow
transmitter in a line ?
Answer Posted / carl_ellis
Configuring the range for a DP transmitter
Open tank:
- Flanged DP transmitter
- high side at lower flange
- no remote seals:
- units: water column units = uwc
- LRV = 0.00 uwc
- URV = physical upper level elevation (uwc) * specific
gravity of fluid
Closed tank:
- flanged DP transmitter
- high side at lower flange
- no remote seals
- dry leg from vapor space above liquid is piped/connected
to the low side
- LRV = 0.00 uwc
- URV = physical upper level elevation (uwc) * specific
gravity of fluid
When the receiver (DCS/PLC/indicator/recorder) receives the
level signal, it converts to physical level elevation by
dividing the process level signal by the specific gravity
and scaling to physical level units.
Volumetric flow rate with DP transmitter on DP flow element:
- units: water column units = uwc
- LRV = 0.00
- URV = maximum DP value at the maximum flow rate stated
on the sizing sheet of the DP flow element
Whether the signal is square rooted in the transmitter or
in the receiver for conversion to flow rate is up to the
plant convention/standards.
