oil, so as to reduce the volume of drained oil. Turn adjusting bolt clockwise to reduce discharge, anticlockwise to increase discharge. Therefore, changing the position of bolt enable discharge approach academic volume and reach the requirements on measurement transducer of national appraisal regulations. As two regulative bolts access to adjusting piston, the adjusting discharge in a circulation per bolt can be calculated in the following formula: △V = 1/2πd12 nt (2--4 ) △V ── adjusting value in per circulation; D1 ── diameter of regulative piston; n ── turning number of adjusting bolt; t ── screw- pitch of adjusting bolt. There is another metal piston measurement transducer in current market. See the Diagram 2-19. Regulative piston is singularly installed in piston rather than connect with rod in this model. Its adjusting value in terms of per adjusting bolt is: △V = 1/4πd2 nt (2--5 ) Common failure and Troubleshooting Metal piston measurement transducer has the two common failures --- accuracy decline and mechanical trouble. Measure accuracy beyond scope The allowed measurement accuracy of fuel dispenser is ±0.3 %, repeated tolerance no more than 0.15 % according to the stipulation of JJG443-98 Fuel dispenser. The maximum allowed tolerance of min. measured valve don’t exceed ±0.5 %，its repeated tolerance no mo fuel dispenser re than 0.25 %. The ratio of maximum flow (Q max.) to minimum flow (Q min.) is 10 to 1. as fuel dispenser leave factory. The ratio should not be less than 5: 1 in inspecting at operation locale. All of exceeded tolerance is regarded as beyond measurement accuracy. There are many elements and reasons resulting in measurement accuracy beyond scope, including unstable hydraulic system (extensive pressure fluctuation), electri fuel dispenser c system failure, th fuel dispenser ick colloid in frictional interface, measurement transducer abrasion, etc. The last two reasons will mainly be introduced in this article.

ce, as in a mall or a department store. But others prefer to do some shopping in the mall and to seek out specialist shops for specific products. “So you have to allow both à la carte and integrated capability,�he says. Secondly, for convergence to work it has to be simple for the consumer. This is something that every technology firm insists is a top priority. But their products, and their users, suggest otherwise. “I m sure if you go to some laboratories somewhere, they can show you caller ID on the TV screen. The challenge is to take the technology and make it really simple, so our mothers and fathers can use it,�says Skype s Mr Zennström. Making free phone calls over the internet has been technically feasible for years, but it only really took off with the arrival of Skype, which made it easy. “We try to make things really simple, so you don t need to be an engineer to set them up,�explains Mr Zennström. Mr Lombard of France Telecom admits that the industry still has some way to go in this regard. The past decade, he says, has seen the introduction of all kinds of wonderful new technologies. “But we have a kind of complexity in all these products that is rather artificial and probably transitional,�he says. Carmakers do not expect drivers to open up their cars and adjust their engines. “If you compare what we are asking customers, we are asking them to enter codes, add fuel dispenser resses, it is far too complex,�he says. What s in it for me? Mike Cansfield of Ovum, a telecoms consultancy, also reaches for an automotive analogy. “Telecoms has historically been technology-led, full of technobabble,�he says. “You have to be able to articulate benefits to encourage take-up.�Consider the windscreen wipers on a car “You could talk about different motors, variable speeds and intermittent wipe fuel dispenser s, but the benefit i fuel dispenser s that you can use the car whatever the weather.�Similarly, he says, telecoms firms have to become more marketing-savvy.
