best quality china made stainless steel Prover tank measure can use for lab 5000 L prover tank

· AISTAR -Calibrated Measures & Volumetric Provers

· Built to NIST Handbook 105-3 Standards, OIML R-120 and API Manual of Petroleum Measurement Chapter 4

· Manufactured of Series 304 Stainless Steel, which resists ordinary rusting, can be easily cleaned, resists organic chemicals, no slag and requires no internal coating. Series 316 stainless steel is available upon request

· Calibration By Standards Traceable to National Institute of Standards and Technology

· Graduated Neck with scale that is sealed

· A butterfly valve is standard with the drain at the center point. This is the most versatile unit for use in the field whether emptying into tank, using a pump or gravity discharge. A ball valve is optional. It is used mostly in laboratory applications or where special application exists. The drain would then proceed at a 7 degree decline with the ball valve near the perimeter of the prover

· Reinforcing bands to prevent distortion of prover when full with liquid and when being transported

· Two spirit levels with seals are used as level indicators for provers more than 18” diameter, otherwise a circular bulls- eye level is installed.

· Two Lifting Loops are attached to top band of prover

· Standard capacities are available from 5 Gallon/20 Liter to 1500 Gallon / 5000 Liter. Call for special volumes.

· All Stainless Steel Provers

· Steel or Aluminum skid

· Three Bolt down - Adjustable Crank Legs to level prover

· Stainless Steel hinged locking cover for top of neck

· Another cover is extended to protect the Gauge Glass from accidental breakage and can be secured with a lock for safety.

· Sight flow indicator for ob- serving fluid flow down- stream of the shut-off valve.

Specifications:

The temperature at which test measures and provers are referenced during calibration and during

use for testing petroleum products is generally 15.56 °C (60 °F). International standards

reference petroleum products to 15 °C. Provers may be used for applications other than

petroleum products or in areas where a different reference temperature is used for petroleum

products. In such cases, the appropriate reference temperature for the application should be

identified and used. For example, the reference temperature for provers used in testing milk is

4.44 °C (40 °F).
