    This device often is installed on check valve, hose pipeline also release certain hydraulic pressure. Pipe Resonance Apart from hydraulic stock, other hydraulic components also cause a certain degree of noise in pipeline, such as vane pump, overflow valve, vapor separator, measurement transducer, solenoid valve and nozzle. Sometime pipe resonance will be generated if the inherent frequency of pipe equivalent to hydraulic pulse resulted from hydraulic components of fuel dispenser. At that time, the normal working state will be affected, which is harmful to staff’s health due to intensive noise. In order to explain this problem, the inherent frequency of pipe is introduced here. Pipe inherent frequency is: ω0 = kπ/2 l2 ·EJgGd+Gj (2-14) In the above formula: ω0 ── inherent frequency of pipe l ── supporting point distance E ── elastic modulus of pipe material J ── inertial moment of pipe section g── acceleration of gravity Gd── weight of pipe per meter Gj──liquid weight in per meter of pipe K── modifying coefficient K= 1-pA+mv/2π2EJA/l2 (2-15) In above formula: A ──pipe section m ──liquid weight in per meter of pipe v ──velocity of flow of liquid in pipe Several relative parameters affect the inherent frequency of pipe in Formula 2-14. Therefore, most manufacturers pay much attention to these elements that affect pipe inherent frequency and pulse frequency of hydraulic components in the design and manufacture of fuel dispenser, making the two fuel dispenser frequencies as much different as possible so as to appear pipe resonance in fuel dispenser. 3. Hose used for fuel dispense fuel dispenser r There are two kinds of hose used in fuel dispenser. one is made according to GB/T10543 Rubber Hose fuel dispenser Used for Refueling and Discharge of Airplane, connected oil indicator with nozzle; the other kind of hose is used in fuel dispenser with vapor recovery device, not only connecting oil indicator with nozzle,

It only exists in the case where one (or more) previously opened transaction session(s) cannot  be closed (see transaction session management page 59): it consists in exchanging messages 9 and  10 specific to this session. In the case of an integrated ATM there can only be one session open; on  the other hand in the case of a stand-alone ATM (terminal) there may be several sessions.   8.4. Message validation   8.4.1. Optional fields   The presence of most of the messages fields described in the chapter Message description from  page 41 onwards is obligatory: the absence of these fields results in the non-validity of the message  received.   In the absence of an optional field the information normally transported by this field adopts a  default value defined in the chapter entitled Data dictionary from page 63 onwards.   8.4.2.
