2. Structure and Advanced Technology of Kometer Electromagnetic Flowmeters
2.1. Main Structure of Kometer Electromagnetic Flowmeters Kometer electromagnetic flowmeters are designed with the following main components:
-
Flow Tube/Sensor Body: Made of durable materials such as stainless steel, impact-resistant plastic, or cast iron, allowing the device to operate stably in clean water and wastewater environments. (HVAC Term: Flow Tube)
-
Flow Sensor: Consists of two electromagnetic coils that generate a magnetic field and two sensing electrodes to measure the voltage generated when water flows through.
-
Signal Processor/Transmitter: Converts the measured data into flow rate parameters displayed on the screen. (HVAC Term: Transmitter)
-
Display: Displays instantaneous flow rate, total flow, and other technical parameters.
-
Signal Connection Port: Allows connection to control systems such as SCADA, PLC via communication protocols such as Modbus, 4-20mA, etc. (Automation Terms: Modbus Communication, 4-20mA Analog Output)
-
Series KTM-800: Electromagnetic flow sensor (Electromagnetic Flowmeter)

2.2. Operating Principle of Kometer Electromagnetic Flowmeters The device operates based on Faraday's law of electromagnetic induction, in which:
-
When conductive water flows through the measuring tube, it cuts across the magnetic field generated by the electromagnetic coils.
-
The movement of the water creates a voltage proportional to the flow velocity.
-
Electrodes on the tube wall receive this signal and send it to the processor to calculate the flow rate.
-
Because there are no mechanical parts in direct contact with the water, Kometer electromagnetic flowmeters have high durability, are not subject to wear and tear, and minimize blockages.
2.3. Kometer's Advanced Technology Optimizes Measurement
-
High-Precision Measurement Technology: low error margin, typically +/-0.5% or lower.
-
Corrosion-Resistant Lining: Protects the sensor when exposed to wastewater, chemicals, and water with impurities. (HVAC Term: Liner Material)
-
Self-Diagnostic Mode: Detects problems such as signal loss, sensor damage, enabling quick maintenance.
-
Smart Connection with SCADA, PLC Systems: Supports remote monitoring, optimizing water flow management.
Thanks to these advantages, Kometer electromagnetic flowmeters are the ideal measurement solution, ensuring high performance, stability, and accuracy for water supply and drainage systems.
3. Applications of Kometer Electromagnetic Flowmeters in Water Supply and Drainage Systems

4. Outstanding Advantages of Kometer Electromagnetic Flowmeters
4.1. Accurate and Stable Measurement
One of the biggest advantages of Kometer electromagnetic flowmeters is their ability to measure accurately and stably with very low error, usually from ±0.5% or lower. Electromagnetic induction technology helps eliminate factors that cause interference, such as impurities in the water, viscosity, and temperature, providing reliable measurement results even in harsh environments. This is an important factor in effectively controlling water supply and drainage processes, wastewater treatment, and drinking water production.
4.2. No Mechanical Parts, Reduced Wear
Unlike traditional mechanical flowmeters, Kometer electromagnetic flowmeters have no mechanical parts such as wheels or vanes, so they do not wear out over time. This not only increases the lifespan of the device but also minimizes malfunctions. The absence of mechanical parts in direct contact with the fluid also reduces the possibility of blockages or abrasion from debris in the water.
4.3. High Durability, Corrosion Resistance
Kometer electromagnetic flowmeters are made from durable, corrosion-resistant materials such as stainless steel, chemical-resistant plastic, or cast iron, allowing the device to operate effectively in any harsh environment, including wastewater with high acidity or alkalinity. This helps the device operate for a long time and saves on maintenance and replacement costs.
4.4. Easy Maintenance and Servicing
Another advantage is that Kometer electromagnetic flowmeters are very easy to maintain and service. With a design that has no moving mechanical parts, checking and maintaining the device becomes simpler, without the need for complex disassembly. In addition, the flowmeter has a self-diagnostic function, helping to detect problems or errors during operation, thereby minimizing downtime and repair costs.
4.5. Flexibility and Connectivity with Control Systems
Kometer electromagnetic flowmeters can connect to control systems such as SCADA, PLC, or HMI through communication protocols such as Modbus RTU, 4-20mA, making it easy for operators to monitor and manage remotely.
