The PD Flow meter is a device that helps in measuring the flow rate of fuels and oils transferred from one container to another; for example, from an oil storage unit to a tanker truck in the authorised fuel distribution industry. These meters are usually mounted on ‘Skids’ in the application areas for bulk metering during fluid transfer operations. When working in these hazardous conditions, you should prefer using a positive displacement PD meter having advanced features and specifications. There are certain factors that should be carefully analysed for selecting these devices for your specific applications. Here, they are:
1. Consider the Size of PD Flow Meters:
A PD flow meter for use in the oil and petrochemical industry is available in different sizes. You should choose the perfect sizing according to the volume of liquid to be transferred within your facility. They come in sizes ranging from 1 to 1/2 inches to allow flow rate ranging from 25-3000 litres per minute.
2. Consider the Meter Reading Display Settings:
When using a flow meter, it is extremely important to understand the meter readings. These devices are available with different display options. You should choose the PD meter that has proper display settings for accurate reading of the values. Preferably, look for a system that has standard counters or mechanical registers with advanced features. These devices have a non-resettable totalizer and resettable display. Also, you can include a mechanical printer for recording specific amounts and there is a preset counter for batch metering applications.
3. Consider the Safety Features:
If you are looking to install this flow meter in hazardous areas, you should ensure it has documented and complete safety certificates for use to guarantee the safety of the operators. Generally, they are installed near electrical equipment like transformers and motors. There are risks involved when operating these devices in such environments.
Hence, you should assess the risk parameters of your site and find a PD meter that can withstand these issues.
4. Consider the Accuracy Range:
Positive displacement flow meters with a higher range of accuracy can ensure flawless metering in your applications. It offers consistency and durability in the performance of a flow meter in the long run. Prefer a system designed to allow maximum accuracy. This can be facilitated by the features like air eliminators and air control valves. Both these features assure accurate measurement during the process of bulk metering. The system should be easy to link with the valve controls through micro-switches. To reduce the inaccuracies, you should invest in a flow meter that can be easily integrated into your existing setup.
5. Consider the Maintenance Requirements:
The smooth functioning of your industrial equipment is imperative. It needs timely maintenance to minimise the downtimes and system failures. Therefore, you should prefer a high-quality product and inspect it regularly to prevent corrosion or failings.
These are the main factors that you should keep in mind when looking for positive displacement flow meters for bulk metering applications.
