Loll transmitter and lug gauge design tips
Surface design or tank design designed by the engineer to display various details of surface equipment (flange size, range) in tanks / drums, their height is used as input for mechanical-static engineers (tank) to further engineer tanks .
Why is this provided?
It is prepared as an input document in the mechanical-static section (tank) to be an accurate and documented tool interface.
These benefits are available to both engineering groups because the details are documented and any changes are tracked by reviewing the document.
Disadvantages / advantages?
For a smaller project, spend less effort than large-scale projects if you do not have a lot of equipment to prepare this document.
The interface between the two strings is simplified and there is no room for differences in inputs and information. Changes will always be traceable. If ambiguity is found, this can be documented and corrected.
What are the main inputs required?
- (P&ID (Design level
- (IPDS (Design level
- (Mechanical data sheet (Design level
- (Piping Specification (Design level
- (Instrumentation Design Basis (Design level
- Client / Process Licensor Specific requirements
What are the different types of tanks?
What are the different types of equipment that can be used in tanks?
- Level Transmitter ( Contact / Non-Contact type
- Level – Differential Pressure Transmitter
- Gauge Level (Magnetic, Transparent, Reflex
Various combinations you can have in the tank (standing tube / straight nozzle)
The equipment level nozzle can be installed directly on the tank.
Figure 1 – Surface transmitter and gauge roller are installed directly on the equipment
Standing pipes are used to install surface tools
LL Level of LT = [(300 mm – 150mm) / 1400 mm] * 100 = 10.71%
Calculate HH Level of Level Transmitter
And HH Level will be at @ 89.28%. ie
