    ents on metrological management. The chapter briefly introduces fuel dispenser’s metrological management and technical requirements, appraisal related and attentions. Article I Metrological management and technical requirements In accordance with The Law on Metrology of fuel dispenser’s legal management mainly includes follo fuel dispenser wing aspects: Model approval, initial approval, subsequent appraisal and inspection in operation. Model ap fuel dispenser proval refers to an entire test, examination and assessment as to new model’s entire performance. Initial approval refers to assess whether or not the fuel dispenser made by manufacturer in accordance with the model having been ratification through a series of testing, as well as metrological performance with relative metrological rules and regulations. Initial approval really has two phases �- approval combined with factory test, and testing appraisal after installation. Subsequent appraisal is conducted after long time since initial appraisal, from which considerable appraisal period is set down according to related requirements. Periodical appraisal is also regarded as the continued subsequent appraisal. Fuel dispenser’s measuring performance within appraisal period needs to be examined, so filling station should deploy self-check standard instrument (no less than 20L) to examine and inspect. Apart from applied to fuel dispenser approval, JJG443-98 also adapt sample testing and pattern evaluation. Although there are two items of accuracy and flow distance ratio conducted in initial approval and subsequent evaluation, there are other technical parameters different from approval as for fuel dispenser made after passing pattern evaluation, including minimum calculated volume and minimum cubic variable. Several items reference to the pattern evaluation and sampling testing of mechanical hydraulic section of fuel dispenser as followed: Accuracy testing The testing’s purpose is to define the flow curve and verify the tolerance scope in which the allowed maximum tol fuel dispenser

    r up to 8  different Prod_Nb could be defined.  The access to this data is defined by the PR_ID address (product identifier). This address key  is used for internal links between databases (product logical nozzle meters). These links  depend on the way the dispenser is built and are dispenser model dependent.  The PR_ID fuel dispenser = 40H is used to ask for all products.  Any attempt to operate on a DB_Ad which has not been implemented s fuel dispenser hould be rejected with  a MS_ACK set to NAK 2 (application non existent on the recipient node).

The Prod_Nb must be unique for   a dispenser (this is controlled by the dispenser before   accepting the Prod_Nb to PR_Id link during the   configuration). Therefore the product database should be   declared to have only one record per unique product. A   write action for a address PR_ID with the Prod_Nb   00000000 means that the associated data must be deleted.   PCD Comment:   It s fuel dispenser

    ees on the payroll—only to discover they have starved new firms of manpower and credit. Big models, which span all the markets in an economy, can make policymakers think twice about the knock- on effects of their decisions. Wassily Leontief was one of the first to do more than just theorise about this tangled web of interdepen fuel dispenser dence. In 1941 he published his book “The Structure of American Economy� which he updated a decade later. fuel dispenser Tucked in the back was a 55cm x 65cm table—too big to be printed in the book itself� showing the flow of commodities and services back and forth among America s households, trading partners and 41 national industries. Of the $5.58 billion-worth of yarn and cloth that passed out of America s factory gates in 1919, for example, $318m was exported, $41m was used up in agricultural production, $31m in making furniture, $6m in the shoe industry, and so on. In Leontief s blueprint, each industry is represented by an equation. The inputs to the industry are entered on one side of the equation, the industry s output appears on the other. Since the output of one industry (steel, for example) serves as an input for another (construction), one cannot solve any equation without solving them all simultaneously. In the palm of their hands Short of good data, and stretched to their computational limits, the early modellers nonetheless had high ambitions. They aimed not merely to understand the economy, but to run it. Leontief s book was translated into Russian; his techniques studied by Soviet planners. Leif Johansen, a Norwegian economist often credited with building the first CGE model, put his handiwork to use at Norway s planning ministry. During the second world war, the stewards of America s war effort turned to the Cowles Commission, an economics brain-trust, to help them ration America s resources. “We imagined that we held the well- being of the economy right in the palms of our hands,�one of the Cowles economists told a journalist, David Warsh. fuel dispenser
