Electromagnetic Flowmeter IZMERKON EM 370
Measuring liquid flow in non-pressurized and gravity-fed systems has always been considered one of the most challenging engineering tasks. Traditional devices often struggle with changing pipe fill levels, but the modern IZMERKON EM 370 electromagnetic flowmeter is specifically designed for such conditions. It is a reliable solution for measuring the volume of water and wastewater in pipelines that are not fully filled, making it indispensable in utilities, land reclamation, and treatment facilities.
The device combines the classic electromagnetic induction method with modern level measurement algorithms, allowing it to provide accurate data regardless of how full the pipe is.

Features of the IZMERKON EM 370 Model
The main challenge of non-pressurized systems is that the cross-sectional area of the flow constantly changes. The EM 370 model handles this thanks to the unique design of the sensor unit.
Key advantages of the device:
- Comprehensive measurement. The device simultaneously measures flow velocity and liquid level, automatically calculating the total volumetric flow.
- No obstructions. There are no protruding parts, blades, or constrictions inside the measuring channel. This ensures no pressure loss and prevents sensor clogging by solid impurities.
- Bidirectional measurement. The device works effectively in both flow directions, which is important for complex hydraulic structures.
- Wide choice of materials. Electrodes can be made from stainless steel, titanium, tantalum, or Hastelloy, allowing measurement of even aggressive wastewater.
- High degree of protection. The remote sensor version can be supplied with an IP68 protection rating, allowing operation when fully submerged in wells or chambers.

General Information and Operating Principle of the Device
Any electromagnetic flowmeter operates based on Faraday's law. A magnetic field is created inside the device. When a conductive liquid passes through this field, an electric voltage proportional to the water velocity arises on the electrodes.
However, in the case of partially filled pipes, velocity alone is not enough. The EM370 flowmeter integrates an additional channel for level measurement. The system determines the pipe fill level in real time and adjusts the flow cross-section calculation accordingly.
This method ensures stable readings at flow velocities from 0.1 to 15 m/s. The medium's conductivity must be at least 5 µS/cm, which corresponds to virtually any technical water and wastewater.
Applications in Various Industries
The versatility and reliability of the design allow electromagnetic flowmeters of the EM 370 series to be used in the most critical areas:
- Municipal sewer networks. Accounting for wastewater in non-pressurized collectors where fill levels vary depending on time of day and precipitation.
- Treatment facilities. Monitoring incoming and outgoing water flow at biological treatment stations.
- Irrigation and agriculture. Controlling water flow in gravity-fed channels and field irrigation systems.
- Industrial wastewater. Accounting for discharges from chemical, metallurgical, and pulp and paper industries.
- Cooling systems. Monitoring return water in open trays and pipelines of thermal power plants and large factories.
Flowmeter Properties and Features
It is important to note that the device maintains accuracy even in the presence of suspended particles or a small amount of foam in the water, which is critical for sewage wastewater.
Technical features of the sensor:
- Материал футеровки: wear-resistant polyurethane or fluoroplastic (PTFE) is used, ensuring the durability of the measuring channel.
- Data transmission interfaces: RS485 is standard, and HART modules can be optionally installed.
- Power consumption: the device is extremely energy-efficient, with a power consumption of less than 20 W.
- Diameter range: the standard range covers pipes from DN200 to DN1000, meeting the needs of both small collectors and large mains.
