Product details

Electromagnetic flow meter

Electromagnetic Flowmeter: SDL-EM20

Magnetic flowmeter details:

1. The principle is virtually independent of pressure, density,temperature and viscosity

2. Superior control through advanced sensor design

3. Even fluids with entrained solids can be metered (e.g. ore slurry, cellulose pulp)

4. Submersible and buriable installation options

5. Intuitive navigation and configuration

6. Free pipe cross-section (CIP/SIP cleaning, piggable)

7. Speed, ease and security in the field

8. No moving parts, Minimum outlay for maintenance and keep

9. Detailed diagnostics for rapid decision making

10. Powerful and flexible transmitter

11. No pressure losses, Very high turndown up to 1000:1

12. High degree of measuring dependability and reproducibility,good long-term stability

Electromagnetic flow measurement has been in use around the world for 50 years and more, as witnessed by the popularity of these meters that continues unabated in virtually all sectors of industry.

The Electromagnetic Flowmeter is the ultimate solution for flow measurement and management and can be used to measureall electrically conductive liquids (> 5 µS/cm) with or without solids, e.g. water, wastewater, sludge, sewage, slurries, pastes,acids, alkalis, juices, fruit pulp, and effluent etc. Its performance adheres to the most stringent global industry standards and is certified to key international approvals.

In the industrial environment, sectors that utilize this measuring principle include: water/wastewater, chemicals,pharmaceuticals, pulp and paper, foodstuffs, etc. Electromagnetic flowmeters are even robust enough to be used in mining.

Proven in the toughest applications, EM20’s rugged, robust and unburnable sensors eliminate the need of expensive meter chambers. Thereby, it provides a long, productive and maintenance-free asset life. Take advantage of its innovative andversatile attributes to achieve interoperability within a wide range of asset management systems.

Load resistance


Basic error

Basic error of the measured value plus ±10µA

Frequency output

For forward direction and reverse direction, the maximum frequency can be set between 1~5000Hz. The output is collector of transistor open with galvanic isolation. External power supply should be less than 30V, and maximum current for the collector is 250mA when it works.

Pulse output

For forward and reverse direction. The pulse can be up to 15000 per second. The pulse width is up to 25ms. The output is collector of transistor open with galvanic isolation. External power supply should be less than 30V, and maximum current for the collector is 250mA when it works. Via an inside pull-up resister, frequency and pulse output can use the inner 24V power supply. The maximum current for the collector is 2.3mA when it works.


Display with English and Chinese, five characters for flow rate and ten characters for volume.


Two alarms are the collector of transistor open output with galvanic isolation. External power supply should be less than 30V, and maximum current for the collector is 250mA when it works.

Alarm output for the following faults: Empty pipe direction, analog exceeds its range, frequency exceeds its range and the fault for magnetic field excitation.

Status input

Communication serial output with RS485. It has protection for lightning strike.


2~100s (90%)


The isolating voltage should be more than 500V between analog output, pulse (frequency output), alarm and ground.
