Calibration Procedure – pH electrode Select two buffers that bracket the expected sample pH. More buffers can be used for greater accuracy over a wider pH range. For best accuracy, use buffers that are no more than 3 pH units apart. Step by Step Procedure 1.Refer PH meter manual for specific details on operating your …
What is Direct Acting ? Â Direct acting means that valves uses a power supply to open and close. Power is transformed into magnetic force,in a plunger type valve,forces a plunger to move and open or close the valve seats. Other direct acting valve operate without a plunger but with same principle of direct power …

P&ID: Schematic illustration of instruments and their interconnection is called P&ID. PFD:Process flow diagram.PFD gives an overview of the plant process.PFD is a simplified version of P&ID. Symbols,circles and lines are used to represent instrument and their interconnection.For identifying instruments and pipe lines tag numbers are used.For reading P&ID(Piping & instrument diagarm) one must be …
