high reliablility water power meter test bench DN15~50,high
high reliablility high precision
long service life
water meter test bench:
1. Brief introduction:
This is bench is designed and manufactured according to national
JJG64-2000 and GB/T778.3-1996. All its actions and impulse
transition are control by computer through RS485. Windows XP
operation platform is adopted. Every data are showed on the
computer .The operater can use Mouse to send to command.
Test report can be printed, saved, and deleted.
This device can be used to test DN15~50mm water meter one by one or
series connection. This is the most advanced water meter test
11. Operation principle:
The device adopt volume principle. That is make the water flow
thought tested meter and go into a container. The compare the
volume of water in the container with the digits on every tested
meter . so the error can be got.
Error =(digits on water meter counter the volume in the container
)/ the volume is the container *100%
The digits of the volume in container is read by optoelectronic
pick-up head and picture technology collection and recognition. The
computer will automatically do calculate and show the error.
1. this test bench is made up of measure container, working bench ,
flow data display system, flow adjust system ,air resource and
2. measure container:
The containers glass body equipped with optoelectronic breaker ,
pick-up haedand water level light.
3. flow display system:
If need to test dripping-proof water meter, another LZB-4 flow
meter is needed.
