Another Italian manufacturer, Piusi, has been a significant role player in the flow meter market for ages. Piusi, known for its precision and versatility, is a prominent choice for various industries, including mining and construction. The compact packaging and high quality of their budget flow meters is suitable for various applications where rugged fluid measurement directly impacts productivity, cost control, and safety.

Being one of the very few manufacturers that still offer mechanical flow meters to complement their digital range, Piusi caters to specific customer needs. Industry favours the mechanical flow meters in scenarios where reliability and simplicity are key factors. They are ideal for measuring low to medium flow rates of liquids like diesel, oil, and chemicals. These meters are often used in scenarios where consistent and straightforward measurements are critical.

On the other hand, Piusi’s digital flow meters exemplify the integration of cutting-edge technology. These meters offer real-time data, programmable settings, and seamless compatibility with many electronic monitoring systems such as the Lumier Hydro Carban Management systems offered by IFS. These control and dispensing systems are becoming indispensable in modern industrial and mining environments, where data-driven decision-making is driving sophisticated cost management protocols.

Liquid Controls: Expertise in Custody Transfer

In the realm of flow measurement, Liquid Controls stands out with its expertise in custody transfer (also called fiscal metering) applications. This expertise is of particular significance in industries where accurate measurements are essential for trade and legal purposes. Industries, such as mining and industrial sectors, rely on Liquid Controls’ precision-engineered positive displacement flow meters. Specifically to ensure that they can measure the quantity of liquid transferred between parties with unparalleled accuracy.

Industries recognize the positive displacement technology used by Liquid Controls’ flow meters for its accuracy, especially in scenarios with varying viscosities and fluid properties. This makes these meters ideal for applications involving the transportation of petroleum products, chemicals, and water. In the context of South Africa, where mining operations often involve the transport of valuable resources, custody transfer accuracy is not only crucial for business operations but also for complying with stringent regulations and contractual agreements.

The LC Meter consists of a housing with three synchronized rotors in cylindrical bores, ensuring no metal-to-metal contact. Each rotor is supported by bearing plates, and they alternate through half-cylinder bores to create a continuous seal. Timing gears are at the rotor shaft ends, with the blocking rotor gear rotating at half the RPM of the displacement rotors. Precision machining ensures tight tolerances without oscillating or reciprocating motion. The design eliminates axial thrust, preventing rotor wear against bearing plates. Oversized sleeve bearings and high-quality materials ensure longevity. This results in the LC Meter offering unmatched accuracy, a long lifespan, and exceptional reliability.

LC meters also comply to both international environmental (ISO 14001:2015) and safety (ISO 9001:2015) standards.

Safety Regulations in South Africa

Safety regulations in South Africa play a critical role in decision making when hazardous substances are managed. The Occupational Health and Safety Act (OHSA) of 1993 sets out the responsibilities of employers and employees to ensure a safe working environment. This includes measures to prevent incidents, injuries, and environmental harm.

For industries dealing with petroleum products or other hazardous chemicals, adherence to regulations such as the Hazardous Substances Act of 1973 is essential. This act regulates the use, handling, storage, and transportation of hazardous substances to prevent accidents, leaks, and environmental damage.

Let’s focus on 2 aspects of this Act:

Storage & Handling:

• The Hazardous Substances Act sets out strict guidelines for the safe storage and handling of hazardous substances. This includes a definition of which substances are hazardous, such as flammable, toxic, or corrosive materials.
• Storage facilities for hazardous substances must comply with specified safety standards. These standards include adequate ventilation, fire-resistant construction, proper labelling, and secure containment to prevent leaks or spills.
• Handling procedures require training and certification for personnel. This ensures they are aware of the risks and precautions associated with the substances they are working with.
• Flow meters play a crucial role in monitoring the flow of hazardous substances during handling processes. They provide real-time data on the volume and rate of flow, helping operators maintain control and prevent accidents or spills.

Transportation:

• The transportation of hazardous substances is a high-risk activity, and the Hazardous Substances Act imposes strict regulations on it.
• You must appropriately mark and equip vehicles transporting hazardous substances with safety features. These include emergency response kits, spill containment materials, and warning placards.
• You need to train drivers and transport personnel to handle emergencies and respond to spills or accidents involving hazardous substances.
• Flow meters are essential in transportation because they allow for accurate measurement of substance quantities being loaded and unloaded from vehicles. This ensures that hazardous materials are transported in the correct quantities, reducing the risk of overloading or spillage during transit.

Additionally, in the mining sector, the Mine Health and Safety Act (MHSA) of 1996 sets out regulations specifically aimed at ensuring the health and safety of workers in mining operations. This includes guidelines for the handling of explosive materials, ventilation, and emergency preparedness.

Flow meters have an impact on the following regulations from the MHSA:

Water management:

• Mines may need to manage large volumes of water, both for mining processes and to prevent flooding in underground operations.
• Flow meters are used to measure and control the flow of water within the mine. This is crucial for maintaining the stability of underground workings and preventing potential hazards related to flooding.
• The MHSA places a strong emphasis on water management to prevent accidents, protect workers’ health, and preserve the integrity of mine structures. Flow meters play a pivotal role in ensuring the efficient use and control of water resources.

Chemical Usage & Dilution:

• Mines often employ various chemicals in their processes, including those for ore extraction and processing. It’s essential to manage the flow of these chemicals accurately to prevent accidents, contamination, and environmental damage.
• Flow meters are used to precisely measure and control the flow of chemicals. This ensures that they are applied in the correct quantities and concentrations.
• Proper chemical management is vital to comply with the MHSA’s requirements for minimizing chemical-related risks and ensuring the safety of workers and surrounding ecosystems.

Emergency Response and Safety Systems:

• The MHSA mandates that mines have robust emergency response plans and safety systems in place to address potential hazards quickly and effectively.
• Flow meters are integrated into safety systems to monitor critical parameters like airflows, water flows, and chemical dosages. This real-time data is essential for triggering alarms and initiating emergency responses when deviations from safe conditions occur.
• Flow meters enable rapid detection of abnormal flow rates. Thus facilitating immediate action to prevent accidents, evacuate workers, or contain hazardous situations.

Flow meters become vital tools for ensuring compliance to the regulations mentioned above. Especiallywhere accurate measurements help with early detection of leaks, spills, and overflows that could lead to safety hazards and environmental contamination. Industrial Fluid Solutions focuses on this aspect by providing flow meters that operate safely in these challenging environments. All the while maintaining the highest standards of accuracy and repeatability required in each.
