Insatech Pharma Flow Calibration Rig for Flow Meter Calibration Introduction

The Insatech Flow Calibration Rig can be used to calibrate flow meters. The mobile calibration rig is easily maneuvered into the production area and allows calibration to be carried out in-line. The in-line calibration will eliminate costs from lost production and will save you hours on the calibration process. Furthermore the flow rig will minimize the risk of contamination by Active Process Ingredients (API).

The Flow Meter Calibration Procedure

After the rig is connected to the Unit Under Test (UUT) and a power supply, it is ready to calibrate. During calibration, water will be circulated through the flow meter as well as a master meter. The calibration rig uses highly accurate and stable Coriolis mass flow meters for exact measurements of the flow. The calibration can be skewed to target a flow range with more points to test this range more rigorously. Another added bonus of the in-line calibration is that you get a check of the total test loop, which eliminates uncertainties that could occur in the lab.

The Flow Calibration Rig has been developed with special focus on operating costs, user friendliness, accuracy and documentation. Furthermore, the rig is a turn-key solution and is delivered tested and calibrated, ready for use. 

User Friendliness

Connections, instruments, and handles are to the extent possible placed ergonomically correct and allowing operation from one side. Furthermore the software is designed with usability in mind making your operator’s user experience easy and effective every time. During the calibration all results are presented on the Human Machine Interface (HMI) after each point of the calibration.


The Calibration Rig is designed to be mobile and the wheels allow the rig to be moved to wherever it is needed. The compact design of the rig means it fits through standard industrial doors and elevators. Furthermore the rig can be lifted by crane using the supplied yoke. To facilitate easy attaching of straps to the yoke, lifting lugs can be mounted in each corner of the rig.

Easy Cleaning

The Flow Calibration Rig is built with materials that are AISI 304 or optionally AISI 316L. Flow meters are made from EN 1.4404/AISI 316L or C22, depending on flow. All piping is made from EN 1.4404/AISI 316L with a surface roughness better than Ra 0.8. This means that cleaning can be performed according to industry practice and all wetted parts are CIP-able (Cleaning-in-place).

Specifications and Accuracy

As a benchmark, the Flow Calibration Rig can calibrate a water flow ranging from 5 to 40,000 kg/h at a pressure of up to 5 bars and temperature of up to 40 °C.Ambient temperature must be between +10 °C and 40 °C. The rig needs a power supply of 400 VAC, 16 A. Other design parameters can be specified. 

The Flow Calibration Rig can be delivered with a traceable DANAK accreditation with an inaccuracy of less than 0.3 % of the measured value.

Is the Standard Solution Insufficient?

If the standard solution is insufficient for your specific use we can, as a pre-order, work out a User Requirements Specification (URS) in accordance with your requirements.

Documentation from Basic to Full Validation

Insatech documents the various components, the interaction between the components and the total delivery as agreed to with the customer. We work according to well recognized standards, e. g. Good Automation Manufacturing Practice (GAMP) and the rig is designed according to both the machinery directive and the low voltage directive.

The extent of our documentation is as per agreement with the customer, and goes from the basic operations manual to full validation in accordance with common practice of the pharmaceutical industry.

Service and Support

Maintenance is limited to a yearly inspection of critical parts, e. g. motor, pump, and the flow meter needs to be calibrated once a year. We can also offer training in the use of the Flow Calibration Rig as part of the delivery. If you choose to sign a service agreement with us, we will perform maintenance on the rig and ensure it functions correctly. Furthermore we will take responsibility for timely calibration of it.
