Yearly I-SYSTEM flow verification is important because it ensures flowmeters continue to operate at optimum condition, in line with operational, ISO audits and regulatory expectations. Over time, accuracy of a flow meter can drift due to wear and tear, process conditions, or environmental factors.
I-SYSTEM flowmeter verifications include electromagnetic flowmeter, paddle wheel flowmeter, open channel flowmeter, ultrasonic flowmeter, turbine watermeter, etc.
Importance A Flow Verification Service
Flow meters are exposed to vibration, temperature changes, scaling, corrosion, and sensor aging. Routine verification helps detect small deviation early, before it becomes costly problem.
Inaccurate flow readings can lead some examples below:
- Incorrect chemical dosing
- Product loss or overconsumption
- Unnecessary energy usage
- Disputes in custody transfer or internal accounting
Many industry operations such as water, wastewater, food and beverage, chemical, etc., require documented reports to submit for their internal and external audits. During the I-SYSTEM flow verification, our technical team use a third-party test equipment calibrated and validated by international recognised KOLAS and SIRIM. The validity of our test equipment is determined by a traceable calibration test done periodically. A professional I-SYSTEM service report is provided after the verification service is conducted.
During a verification service, we assess the flow meter’s sensor, grounding, signal stability, and installation conditions. Identifying issues early can prevent sudden failures and extend the service life of your flow meters. A planned yearly verification is less disruptive than emergency troubleshooting. This allows maintenance teams to schedule corrective actions during planned shutdowns instead of reacting to unexpected meter failures.
Scheduling A Flow Verification Service
When planning a yearly flow verification service, our team will coordinate with the site operator to make sure we can perform the verification with minimal process interruptions. Our test equipment is non-intrusive ultrasonic flow meter, allowing verification without dismantling the running flow meter.
To ensure that the service is conducted efficiently, we will prevent servicing during operation times that have unstable flow, air entrainment or process fluctuations that can affect results. Here are some tips to prepare the site for a successful verification:
- Ensure that verification is done during stable process conditions
- Conduct during planned shutdowns or maintenance windows
- Flow meter and designated pipeline is accessible or isolated
- Clean or flush pipes if fouling is expected
- Operations and safety teams are notified about the verification service
