Fixed type prover tank

Provers (proving tanks) are bottom-drain volumetric measures with or without a graduated bottom-neck Provers may be free-standing or enduringly mounted on a truck, platform or trailer.
The standard measures in stainless steel are 304 and 316. The available regular volumes are 50 liters to 5000 liters.
You can also request customized equipment.
All of the above volumes can be built according to the natures of the metrological authorities in the country they will be used.
A Prover Tank consists of a cylindrical shell welded between two conical ends, which ensure smooth flow of liquid while draining the tank. Fitted to the bottom cone are a T-joint (where inlet and outlet isolation valves can be fitted) and a drain valve to assist in filling and draining of the tank.
The top cone is fitted with a neck tube, having a conical top cover to prevent ingress of dirt in the tank. A graduated glass tube is externally fitted to the neck tube, which indicates the liquid level in the neck tube. Graduations on the tube correspond to the volume per unit height of the neck tube.
The cylindrical shell has a manhole fitted with a bolted cover, which can be opened for internal inspection, painting. A displacement tube arrangement is provided on the top cone to adjust the internal tank volume with the tank capacity mark on the graduated glass tube. For accurate adjustment of tank level, rest pad is fixed to the top cone for keeping level bottles.
The body also has two thermos wells capable of accepting mercury in steel type thermometers. A baffle plate provided at the point of liquid entry in the bottom cone, prevents swirl or vortex formation and related trapping of air in the liquid. The entire tank is erected on a sturdy steel channel frame, which can be either grouted (for a fixed Proving Tank) or bolted to a movable trolley (in case of a mobile Proving Tank).
In the latter case, the trolley comes with a tow bar and leveling screw jacks. The choice of a centrifugal pump with motor to fill or drain the liquid is optional, both for fixed or mobile tanks.
We can produce traceability certificate form NABL accrecrated LAB.
