Reliable Flow and Pressure Monitoring for a Municipal Water Project in Ecuador
Electromagnetic flow measurement supports continuous monitoring at an outdoor outlet pipeline
-
Project Overview
A municipal water project in Ecuador required a dependable way to monitor both instantaneous and accumulated flow at an outlet pipeline. The contractor needed instruments suitable for continuous outdoor operation in a humid environment, with standard analog and digital communication for integration into the monitoring system.
Supmea supplied an electromagnetic flowmeter together with a pressure transmitter. The selected configuration combined a rubber-lined flow sensor, IP65 protection, 4-20 mA output, and RS485 communication to support real-time flow and pressure visibility across the specified operating range.

Supmea Solution
The measurement package was selected around the hydraulic conditions, installation environment, and required system outputs. The electromagnetic flowmeter provides continuous volumetric flow measurement for conductive water without introducing a moving component into the flow path. A pressure transmitter complements the flow measurement by providing pipeline pressure data at the same monitoring point.

Why This Solution Fits Municipal Water Applications
Municipal water networks need stable flow and pressure data for operational control, distribution monitoring, and maintenance planning. By combining electromagnetic flow measurement with pipeline pressure monitoring, operators gain two complementary indicators from the same process area. Standard 4-20 mA and RS485 outputs also simplify connection to local control, display, or supervisory systems.

Recommended Products
The following product categories can be presented as related recommendations beneath this case. Final selection should always be confirmed against the medium, pipe size, flow range, pressure, installation conditions, power supply, and required output protocol.
SUP-LDG / A100 Electromagnetic Flowmeter
Recommended as the core flow-measurement option for conductive water in municipal supply, treatment, and distribution pipelines. It is suitable for applications that require continuous flow indication, accumulated flow totals, and integration with a control or monitoring system.
Recommended for monitoring pipeline pressure alongside flow. Combining pressure and flow data helps operators assess pump performance, distribution conditions, abnormal pressure changes, and overall pipeline operation.
Remote Electromagnetic Flowmeter
Recommended when the pipeline is installed in a chamber, low-lying area, or location where the display is difficult to access. Separating the converter from the sensor can improve display visibility and simplify routine operation in challenging installations.
Recommended when the project requires local display, accumulated-flow review, trend records, or centralized data collection in addition to the transmitter outputs. The receiving device should be selected to match the available 4-20 mA or RS485 signal.
