Overview: This case study explores the successful export of electromagnetic flow meters by Zero Instrument Corporation to the Philippines. The selected products were from the Z100E series, which were chosen due to their reliability, technical specifications, and adaptability to the water management sector in the Philippines, specifically for wastewater measurement applications.
Project Background: The Philippines, like many developing countries, is experiencing rapid urbanization, leading to increased demand for efficient water and wastewater management systems. The client in the Philippines required electromagnetic flow meters capable of accurately measuring wastewater flow, resistant to corrosive conditions, and operating within varying temperature and pressure ranges.
Products Supplied: Zero Instrument Corporation provided several models from the Z100E series, which included:
- Z100E-LDG-40S-M2F012P1N (6 units)
- Z100E-LDG-50S-M2F012P1N (4 units)
- Z100E-LDG-100S-M2F012P1N (4 units)
These models were selected due to their suitability for measuring wastewater and the specific range and conditions outlined by the customer.

Challenges Addressed:
Corrosive Environment: Given the wastewater composition, selecting materials resistant to corrosion was critical. The use of 316L stainless steel for electrodes and PTFE for the liner ensured longevity and consistent performance.
Accuracy in Variable Conditions: The flow meters provided had high accuracy (0.5% grade) even in fluctuating flow conditions. This precision was crucial for ensuring accurate billing and monitoring of wastewater flows.
System Integration: The client in the Philippines required the flow meters to be integrated into an existing monitoring system. The MODBUS communication protocol used by the Z100E series allowed seamless integration, providing real-time data on flow rates, forward and reverse flow volumes, and other important parameters
Installation and Operation: The electromagnetic flow meters were installed across several wastewater treatment facilities. The design, including the compact and remote versions, allowed for flexible installation in various locations.
Each flow meter was calibrated before shipment to ensure optimal performance. During installation, care was taken to ensure sufficient straight runs of piping to avoid measurement errors due to turbulence.
Client Feedback: The Philippine client reported significant improvements in monitoring and managing wastewater. The high accuracy, durability, and ease of integration of Zero Instrument’s flow meters led to more efficient operations and accurate data collection. Moreover, the robust construction of the meters ensured minimal downtime, even in harsh environments.
Conclusion: Zero Instrument’s Z100E series electromagnetic flow meters successfully met the client’s needs in the Philippines, providing accurate, reliable, and durable solutions for wastewater flow measurement.
The deployment of these meters has contributed to better resource management and operational efficiency in the Philippine water management sector.
