Prover
tank
1.sepcification
Manufacture | Haixing Eastern Measuring Instrument Co., Ltd |
Brand | DONGFANG (EASTERN) |
Volume | From 1L to ****0L (or Gallon) |
Material | Stainless steel AISI type **4 or AISI type **6 |
Uncertainty |
First class: 0.**5% Second class: 0.**5% Third class: 0.*5%*0.1% |
Certificate | Issued by NIM, Bureau Veritas or other third parts. |
2.Regulation
1). The maximum
permissible error :
±0.**5%(first class), ±0.**5(second
class), ±0.***0.1(third class).
2). Graduation volume of prover
tank cannot be greater than the nominal capacity of
0.**5%.
3). Body material of prover tank
applies 1Cr*8Ni9Ti stainless steel.
4). The outer of prover tank
should be smooth touched by hand, and the inwall should be
polished to ensure that the amount of liquid residual is minimum
in tanks.
5).Metallic
material adjustable boltshould
be installedon
the legs of prover tank , and directly linked with the ground for
adjusting ground level and antistatic
purposes.
6). The prover tank for detecting
oil should be installed inlet tube to prevent
foaming.
7). The angle of cone and the
lower cone should be less than
**0°.
8). To ensure that the prover
tank is level, two mutually perpendicular horizontal directions
of the main body is mounted adjustable 0.*5mm/m tubular spirit
level.
9). In order to adjust the level
easily, a spinner valve is installed at the bottom
of neck of prover tank.
*0). The length of calipers are
determined according with the requirements, nominal capacity
level scale should be located in the middle of neck
measurement.
*1). In the neck reading
measurement site shall be equipped with a level tube, which is
made by colorless transparent rigid glass. The diameter inside
the tube is between DN 5.6~*6 mm and should be uniform and no
defect.
*2). Caliper and cursor require
Chrome Process, and the zero of caliper installation position
should be located at the bottom of the neck measurement scale.
The reading of caliper should be clear enough, and graduation
width should not greater than 0.*5 mm.
*3). Cursor to be installed in
parallel with the plexiglass loop, with the graduation width less
than 0.*5 mm, and the level tube is located in the plexiglass
loop.
*4). The manufacturing of prover
tank should apply the method of artificial aging method to
eliminate stress, which is good for preventing the deformation
due to the change of stress in the process of
product.
*5). The filling or draining
medium process cannot have leakage. The connection between valve
and body tank should have secure measures and be locked to
prevent the prover tank volume changes due to the loosening of
valve.
*6). Gas exhausting capacity
should no more than 0.2 graduation volume. Prover tank in the
trickle state waits 2 min and cannot have a continuous flow or
intermittent surge.
*7). Ensure that the mechanical
properties of prover tank and the maximum working pressure should
be greater than *0KPa.
*8). If the prover
can complies with additional requirements, the truck and prover
tank can be designed as an integral structure.
About us
Our company has been specializing in metering
systems since ***2 founded. We've been in the market and building
volumetric standards and prover tanks for over *0
years.
All of our products are made to have
traceability to international standards and calibration
regulations established by different
authorities.
Our principal activities involve equipment
engineering and manufacturing for industrial processes developed
in an integrated plant. We are experienced in working with carbon
steel, stainless steel and non-ferrous
materials.
We have been developing these activities in
different countries and even in very different industries
sometimes related to oil, sometimes petrochemical and sometimes
chemical areas.
In order to satisfy our customers
requirements, our main active is that we design and manufacture
the prover tanks specially for each demand. We are all about
innovation and productivity. We are growing as a leader company
all over the world by the day.
We are also offering control services,
reports on technical conditions and calibration of flowmeters
installed in tank truck loading plants, meters and meter provers
for metering systems in pipe line, and prover
tanks.
