The E+H 53L electromagnetic flowmeter, as a versatile standard sensor, is suitable for the water and wastewater industry. It features a loose flange process connection, allowing for flexible installation that is not affected by the installation of pipeline flanges. Combined with the Promag 53 transmitter's touch control, 4-line backlit text display, and advanced software functions such as filling, electrode cleaning, or advanced equipment fault diagnosis, the Promag 53L provides the most accurate measurements for the most complex and demanding operational tasks.

Here's a crisp rundown of the Endress+Hauser Promag 53L key features:

Non-intrusive design: No moving parts, reducing wear and maintenance.

Flexible sensor construction: Lap-joint flanges for DN <350 and fixed flanges for larger sizes—saves weight and eases installation.

High accuracy options: Standard ±0.5% o.r., with enhanced options down to ±0.2% o.r.

Advanced diagnostics: Built-in diagnostic tools for status monitoring and error detection.

User-friendly interface: Backlit 4-line display with intuitive touch control.

Broad material compatibility: Multiple liner and electrode options for aggressive or abrasive media.

Bidirectional flow measurement: Independent of pressure, temperature, and viscosity.

Global approvals: CE, cCSAus, ATEX, and other certifications for hazardous areas.

Frequently Asked Questions – Promag 53L

1. What media can the Promag 53L measure? 

It’s ideal for conductive liquids, especially in water and wastewater applications. It handles aggressive and abrasive fluids depending on liner and electrode materials.

2. Does it require straight pipe lengths for accurate measurement? 

Yes. For optimal accuracy, a minimum of 5× DN upstream and 2× DN downstream straight pipe is recommended.

3. Can it measure flow in both directions? 

Absolutely. The Promag 53L supports bidirectional flow measurement with independent totalizers for each direction.

4. Is it suitable for hazardous areas? 

Yes. It comes with ATEX, IECEx, and cCSAus certifications for use in hazardous environments.

5. What communication protocols are supported? 

Standard output includes 4–20 mA HART, with optional PROFIBUS DP/PA, Modbus RS485, and FOUNDATION Fieldbus.

6. How is the device configured? 

Via the 4-line backlit display with touch control or remotely using configuration tools over supported protocols.

7. What’s the difference between Promag 53L and Promag L 400? 

The Promag L 400 is the newer generation with enhanced diagnostics, Ethernet-APL support, and improved energy efficiency. It’s the recommended successor for new installations.

8. Can I replace the electrodes? 

Not on the 53L. Electrode replacement is a feature of some other models like the Promag W with optional exchangeable electrodes.

9. What’s the maintenance requirement? 

It’s maintenance-free under normal conditions due to its non-intrusive design and lack of moving parts.

10. Is there a compact and remote version? 

Yes. The transmitter can be mounted directly on the sensor (compact) or remotely for easier access in tight or hazardous spaces.
