 ZBWJ-90/99 meter is a new flow concussive Meter, it has
the advantage of low
Power loss, high measure precision, wide measurement
rang, low request of setter, low pressure loss, high
resist destabilization ability, easy to operation and so
no, and main used to account the working conditions
volume and volume flow of natural gas, coal gas,
ammonia gas and compressed air etc in the industry
pipes.
Second
、functional
characters and technical parameter.
1.
measurement media：
natural gas, coal gas, ammonia gas, compressed gas and
other gas
2.
ZBWJ-90 combines flow rate transducer with
intelligence flow rate integration Meter. And thus, the
working conditions flow rate can be showed and exported.

two row liquid crystal showing accumulation flux
and instant flux.
4.
when +3V lithium cell supply power inside ,
average work flux is 38μA, when +24VDC supply power
outside, the interior power can switch automatically
5.
when the meter is power-off, the inside
parameter can conserved for a long time
6.
wide measurement rang, the degree reach10：1~20：1
7.
the frontal straight pipe just 3D, the latter one
just 1D can insure the meter’s precision
8.
There are no mobile unit in the transducer, the
unit detected is not contact with medium directly,
stable abilities, high reliability and long service life

Exactitude: The ± is 1.0%, ± 1.5%;
repeatability,Designation value ± is 0.3%.
