Endress Hauser Promag H 300 DN65 Hygienic Flowmeter for High Throughput Filling Lines in Stock

DN65 Promag H 300 Stocked for High-Throughput Filling and Dairy Mains

October 2026 — The largest bore in our current stocking position is the DN65 (2-1/2 inch) Endress+Hauser Proline Promag H 300, order code 5H3B65-AAIBAEAFBAFDCS0BA2. At this size the question is no longer resolution but throughput: how much product the line can move before the meter costs pressure, and how fast a filling head can be recommissioned after a product change.

Dairy, juice and beverage mains that feed high-speed fillers usually run close to their hydraulic limit. Any constriction in the measuring point is paid for continuously, in pump energy and in reduced filling rate. A full-bore electromagnetic sensor with a PFA liner avoids that trade-off entirely.

Throughput and pressure loss

• Full-bore design, no cross-section constriction, so line pressure is spent on product rather than on the sensor
• Series measuring span reaches 600 cubic metres per hour, with the achievable band set by the DN65 bore
• Bidirectional measurement independent of pressure, density, temperature and viscosity, so recipe changes need no recalibration
• No rotating parts and no shaft seal, which matters where oxygen pickup has to be avoided in beer and beverage transfer

Commissioning and washdown

The compact dual-compartment transmitter has a backlit display with touch control and WLAN access, so parameters can be set from a tablet without opening the housing — useful when the instrument is mounted high on a silo line. Access is from one side, the housing is rated up to IP69 for washdown areas, and a remote display variant is available for instruments installed inside cladding or on a mezzanine. Heartbeat Technology produces a verification record for QA without dismantling the line.

Typical installations

Milk, cream, whey and cultured product mains; juice, concentrate and syrup transfer into blending or filling; CIP return headers on large tanks and silos; and brewery transfer lines where the sensor sits between a fermenter and a centrifuge. In each case the same reasoning applies: the instrument should not be the narrowest point in the line.

Service and spares

The unit is delivered new against the order code above, in original factory packaging, with a 12-month warranty. Seals, grounding rings and connection adapters are available as separate items — send the serial number and we will match the correct spare rather than guess from a photograph. Stock normally ships in three to five working days, with factory builds at roughly six to eight weeks.
