Introduction Zero Instrument, a leader in precision measurement solutions, successfully facilitated the export of split electromagnetic flowmeters to a major client in Trinidad and Tobago. This case study highlights the technical specifications, installation process, and the benefits delivered through this project.
Client Requirements The client required a reliable flow measurement solution for industrial fluid management. The key demands included:
High accuracy of flow readings.
Field display for easy on-site monitoring.
Compatibility with a 24V DC power supply.
Analog output for integration into existing systems.
Durable materials to withstand challenging environmental conditio
Product Overview The chosen solution was the Zero Instrument split electromagnetic flowmeter, model LDG-080, tailored to meet the following specifications:
Accuracy: ±0.5% of rate, ensuring precise measurements.
Display: Equipped with a field display unit for real-time data.
Power Supply: 24V DC, suitable for industrial power systems.
Output Signal: 4-20mA analog current output, facilitating seamless integration with other control systems.
Body Material: Carbon steel, providing a robust and cost-effective option.
Lining: Neoprene, ideal for applications involving water and mild chemicals.
Electrode Material: 316L stainless steel, known for its resistance to corrosion and longevity.
Connection Type: American standard 300lb flange without paired flanges.
Temperature Resistance: Operable in temperatures ranging from -20°C to +60°C.
Protection Level: IP65, ensuring protection against dust and water ingress.
Cable: Standard 10-meter cable for connection between the sensor and transmitter.
Pipe Size and Range: DN80 with a measurement range of 9-90 m³/h.
Weight: 20 kg, allowing for ease of transport and installation.
Implementation and Challenges During the planning phase, considerations were taken to ensure the installation site would maintain a fully filled pipe, avoiding issues with flow accuracy. Additionally, to prevent electrical interference, the installation team ensured the flowmeter was positioned away from high-frequency equipment.
One notable challenge was the client’s operational need for robust, continuous monitoring. The solution provided an ideal match with its durable carbon steel body and neoprene lining, capable of handling variations in fluid characteristics and ambient conditions.
Installation and Calibration The installation process followed these key steps:
Site Preparation: Ensured 3 pipe diameters of straight run upstream and 2 downstream for optimal performance.
Mounting: The DN80 flowmeter was securely mounted with the provided American standard flange connections.
Wiring: Connected the device using the supplied 10-meter cable to a 24V DC power source, confirming the integrity of the 4-20mA signal output.
Calibration: Conducted an on-site calibration test, validating a ±0.5% accuracy, with a range of 9-90 m³/h as required by the client.
Results and Benefits The deployment of the Zero Instrument electromagnetic flowmeter resulted in the following benefits:
Enhanced Measurement Accuracy: Provided consistent and reliable flow readings within the specified accuracy.
Operational Efficiency: The field display allowed operators to monitor flow rates in real-time without reliance on external displays.
Integration: The 4-20mA output signal facilitated seamless integration with the client’s existing data systems.
Durability and Reliability: Withstood environmental conditions due to its carbon steel body and neoprene lining.
Conclusion The export and successful installation of Zero Instrument’s split electromagnetic flowmeter in Trinidad and Tobago showcased our commitment to delivering high-quality, reliable flow measurement solutions tailored to client needs. This project reaffirmed Zero Instrument’s capacity to meet complex industrial requirements and fostered a strong client relationship built on trust and performance.
