Instrumentation controls the operation of process columns. Instrumentation is used to monitor and control the process plant in the oil, gas and petrochemical industries. . Instrumentation ensures that the plant operates within defined parameters to produce materials of consistent quality and within the required specifica
All oil tankers with a gross tonnage of larger than 150 must have efficient Oil Discharge Monitoring Equipment on board. [3] [4] The oily discharge is sent out to sea through a pump. [5] The oily mixture has to pass through a series of sensors to determine whether it is acceptable to be sent to the discharge pipe. [6]
The transformer oil testing device measures and reports the root mean square value of the breakdown voltage. After the transformer oil test is completed, the insulation oil is stirred automatically and the test sequence is performed repeatedly: typically 5 repetitions, depending on the standard.
This calibration generally takes place in a lab, but can be tested by use of a three-sample liquid aboard the vessel. If the OCM ends up sampling a certain amount of heavy oil, the OCM will be fouled and it will need to be flushed or cleaned. [4] Shipboard engine room
The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...
A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston. Deadweight testers are secondary standards which means that the pressure measured by a deadweight tester is defined through other quantities: length, mass and time.
Oil content meters measure how effective the oily water separators on a ship are functioning. [6] If the OCM computes that the oily discharge is above the 15 ppm standard, the oily water separator needs to be checked by the crew. There are three types of oil that the oil content meter needs to check for and they are fuel oil, diesel, and ...
The term "fiscal metering" is often interchanged with custody transfer, and refers to metering that is a point of a commercial transaction such as when a change in ownership takes place. Custody transfer takes place any time fluids are passed from the possession of one party to another. [2]
