RIGCHINA® 1. Summary This product is mainly used to measure the density of drilling fluids and other fluids. Compare with the RCMB model balance, this instrument can make the gas present in fluids released or compressed by virtue of exerting a pressure to the fluids and minimize the influence the natural gas or the air mixed in fluids to the density measurement of drilling fluids, so that the true density of fluids can be measured. The instrument is characterized by the stable measuring data and high precision. It has been widely applied in the oil fields, geological exploration and laboratories...

Balanced tube Adjustment block (lead particles) Cover screw Knife edge Regulating knob Tighten screw Working principles The Model RPMB-31 Mud Balance is an instrument with multiplying lever. The horizontal bubble kit id mounted on the upper lever of knife edge. When the bubble is in the middle position, the lever will be in the horizontal position. The balance ruler is laid on fulcrum of supporting base. The rider can be moved flexibly on the ruler. 5. The operations of the instrument (1) The base of instrument should be placed on a horizontal plane. (2) Loosen to compressed cap and remove cup...

RIGCHINA® (5) Aim the knife edge at the fulcrum and place the knife edge on supporting base. (6) Move the rider nearby the knife edge and then move it slowly towards the right until the balance ruler maintain the horizontal balanced location. (7) The carved line corresponding to the left sideline of the rider is the density value of the fluid tested. (8) Loosen the compressed cap, remove the cup lid and discharge the drilling fluid. Wash the cup and cup lid and smear the waterproof lubricating oil on the one-way valve. Unless calibrating the instrument again, do not open the plug on balanced...
