a. Oval flow meter measurement accuracy is high, the basic error is generally 0.5% R, special up to 0.2% R or higher up special request. Particularly suitable for use in sites where high precision measurements are required.
b. there is no requirement for the viscosity of diesel oil (high viscosity can also be accurately measured)
c. Pipe vibration and interference at the installation site have no effect on this flowmeter. Oval gear flow meter do not need straight pipe requirement.
d. with on-site flow direct reading with mechanical register, no need for external power supply, you can measure the cumulative total, clear display, easy to operate.
e. Currently China oval gear flow meter manufacture develop oval meters with more powerful functions, such as digital display, 4-20mA output or pulse output, RS485 and even Hart protocol.
1. The diesel oval gear flow meter structure is complex in design, large in volume, bulky, especially large-diameter flowmeter, which is bulky and has a very high transportation cost comparing with liquid turbine flow meters which is also a kind of light and cheap diesel flow meters.
2. Only for clean diesel. If the diesel
contains particles and dirt, the filter must be installed upstream, otherwise
the oval gear will be damaged by the particles.
Silver Automation Instruments often receive oval gear flow meters for diesel flow measurement, below is one typical inquiry case:

In the past, China's process instrumentation mainly relied on imports, such as Japanese or European and American brands. For the past 20 years, China's instrumentation technology has continuously improved the technical performance of diesel flowmeters by continuously learning European and American technology and a large number of field application practices. At present, China's oval gear flowmeter manufacturers can produce PD flow meters with stable performance, the price is very cheap, and the delivery time is also very fast.
