58Flow Measurement of Engine Oil
One for the automotive engineers to measure the flow of the most difficult operating conditions is to measure the oil flow. With the engine mounted on a test bench to combine dongryeokgye, and slightly easier job, but the available space, and no one be careful, less choice and requires the installation of the flow measurement system. The flow of instruments for measuring vehicle power requirements of the engine bay, under the harsh conditions required for the installation due to limited space and a hat are required.
What is the flowmeter options? Well, that's how high industry standards, but they are not correct. We take a look at several options.
(1) positive displacement meter, meter gear, piston meters, or helical screw to be in the form of the name can have a few. Typically, the high side on the cost of these meters is relatively high because of a problem when you installed was a drop in pressure can cause. Even if they slide feet across a very wide range of viscosities low viscosities not operating in good pain. Depending on the size of a variety of meters, but is often installed without any need for flow conditioning was fine. House, but not by the engine test is an ideal solution.
(2) turbine flow meter, typically one of the most widely used measure of the flow of oil flow meter, mainly because of its low cost and small size. They can be purchased relatively easily from the manufacturer's host, so the oil is not fatal to the performance management system apryeokcha. They profile the effects of oil and fluid flow, so it also installed 51 in a wide range of upstream and downstream flow, flow meter calibration and conditioning is important to separate the tube. To ensure accurate results when used as soon as it is installed close to match conditions is essential. Quite often the flow of calibration laboratory specializing in the same engine oil, the same operating temperature compensation and the same engine in the flow meter and installed outlet to connect to the entrance to the party. Sometimes, as part of this assembly, the engine oil cooler and oil filter assembly of the easiest and generally preventing the flow of oil to be the engine can have a suit. A lot of water in the engine oil flow meter manufacturer, if you are using a very large can lead to the failure to provide a calibration certificate.
(3) Coriolis meters. It's the only suitable for fixed installation is a very good high-precision meters. These meters high maintenance costs and the size of a large turbine and positive displacement meters in comparison. This indicator, as well as the last 10 years, but still poor installation, has a tendency to measure vibration, and zero-drift errors can be said. To the best use of the test bench, where they immediately and permanently installed tube model is generalized now, they're strong and excellent low-pressure also provides rangeability.
(4) attribute a drop in pressure. Due to the insertion of the oil flow meter without affecting system performance measurement is a common way to get more and more. Individual components of the system to the flow of engine oil pressure, eavesdropping, and the location is part of the flow required for each engine on a drop in pressure at a temperature of the oil flow to the bench for the calibration is a specialized organization. Each system features is a reassembled the engine and test, and recorded and then used to measure the flow pressure is derived. This is typically an important engine lubrication surveys, where the insertion of Flowmeters affect oil flow that was harmful to the system is used.
(5), clamp meters in ultrasound. Even if a device does not interfere with the installation requirements that the pipe, it means that the system's interference in the measurement system 51. Buy high, and the participants for these applications are not well-tested, but the most expensive going more quickly than other technologies.
How to measure the flow, operating temperature range to eat in mind the needs of the level and flow meter calibration, and a good nearest to measure the flow of the arguments is essential to take action. Engineers to study the flow of a relatively new engine lubrication Compensation Research Institute, who measured the flow of suitable applications need to have the budget and on the type of flowmeter for hardware inventory, the best advice to find a solution to be in a good position.
I live in a different issue. To measure the flow of oil is a very complex nature of running the oil flow from the engine to get the exact numbers, meaning it's hard to notice the sound engineering, engineers can create a measurement process was for the judge. I like to go into depth is also 51, oil temperature, flowmeter and the performance of the 51 pumps, oil aeration, hysteresis effect and relief valves, fuel dilution effects, engine oil level, meter installation work and the following series of discussions The meaning of these parameters continue to be a bit more specific.
