Key Advantages of the E&H 5H2B Two-Wire Technology

The E&H 5H2B offers unique benefits that differentiate it from traditional four-wire electromagnetic flowmeters:

1. Genuine Loop-Powered Operation

With true two-wire technology, the 5H2B is powered directly from the 4-20 mA signal loop, eliminating the need for separate power supplies and reducing installation costs . This makes it ideal for remote locations and skid-mounted systems where power availability is limited.

2. Intrinsically Safe Design (Ex ia)

The loop-powered design inherently supports intrinsic safety, allowing the 5H2B to be installed directly in hazardous areas (Zone 0/1) without complex and expensive explosion-proof enclosures .

3. Energy-Saving Flow Measurement

The reduced bore design creates no pressure loss, resulting in significant energy savings over the lifetime of the instrument .

4. Separate Connection Compartment

The dual-compartment housing allows for convenient wiring—the electronics remain sealed and protected while terminations are being made .

5. Heartbeat Technology

Built-in verification allows for on-demand diagnostics without process interruption, supporting predictive maintenance strategies and reducing unplanned downtime .
