Calibration Pot

In chemical injection packages, calibration pots are used to:

• test injection pump flow rate
• confirm actual dosing vs. setpoint
• optimize chemical usage
• improve process reliability
• avoid under dosing or over dosing
• detect pump performance drift over time

It is one of the most practical tools for accurate injection system control.

A calibration pot works by collecting liquid in a transparent measuring tube (or calibrated vessel) for a fixed duration (usually 1 minute). Since the pot has graduated scale markings, the operator can directly read the collected volume and convert it into flow rate such as ML, LPM, LPH, or GPH.

Over time, metering pumps may show variation due to:

• suction fluctuations
• valve wear
• chemical viscosity changes
• diaphragm wear / seal wear
• operating pressure change

Periodic calibration ensures the injection pump delivers consistent flow and prevents chemical wastage, process deviation, and equipment damage.

Calibration pots are commonly used in:

• Oil & Gas chemical injection systems
• Offshore platforms
• Refineries & petrochemical plants
• Water and wastewater treatment
• Power plants
• Fertilizer and chemical plants
• Industrial dosing and metering applications

They are essential wherever dosing accuracy matters.

Petronash calibration pots are robustly designed for:

• offshore salt atmosphere
• onshore extreme temperatures
• harsh field handling conditions
• continuous plant operation

The design focus is durability, operator safety, and long-term accuracy under real site conditions.

Petronash calibration pots are designed for:
1 minute test duration (default)

This makes it easy for operators to conduct routine pump flow tests quickly and consistently without disturbing plant operations.

Petronash calibration pots are available in a wide range:

100 ML to 70,000 ML
(Other volumes can also be supplied on request.)

This allows selection based on pump capacity and flow rate range.

Petronash provides direct scale readings in multiple units such as:

• ML
• LPM
• LPH
• GPH

This is highly user-friendly and reduces calculation error, especially during routine calibration checks by operators.

Petronash calibration pots can be supplied in multiple corrosion-resistant materials such as:

• CS (Carbon Steel)
• SS316L
• Monel 400
• Inconel 625
• other alloys on request

Material selection depends on chemical compatibility, offshore conditions, and project specification.

Petronash calibration pots are available in multiple connection sizes:
½”, 3/4", 1", 1½”, 2" - (Other sizes on request.)

End connections include:

• Flanged
• Threaded

This provides flexibility for integration into different piping and package layouts.

Petronash calibration pots are designed with operator safety as a priority:

• enclosed design for safe operation
• stainless steel glass protection cover
• clear scale graduation visibility
• stable installation readiness for onshore/offshore applications

This ensures safe handling even in harsh operating areas.

Petronash calibration pots are designed for accuracy and long-term field use, offering:

• direct readable graduations (ML, LPM, LPH, GPH)
• offshore-grade robust construction
• flexible material options for chemical compatibility
• safer enclosed structure
• customization for volumes and connections

This makes Petronash calibration pots suitable for EPC projects and critical dosing applications.

Yes. Petronash offers both standard and customized designs including:

• custom volume capacities
