E&H 8A3C Coriolis Mass flowmeter

n the realm of precision process instrumentation, the E&H 8I5B Coriolis mass flowmeter stands as a pinnacle of engineering, specifically designed for demanding applications requiring low pressure loss and gentle fluid treatment. As a premier supplier, ST-YUKE CO., LIMITED is pleased to present an in-depth technical analysis of this exceptional instrument. The Promass I 500 series, featuring the 8I5B, utilizes a straight, single-tube measurement system constructed entirely from titanium, ensuring both durability and cleanliness .

Product Series Overview

The device family is structured by nominal diameter, catering to a wide range of flow rates. The complete portfolio includes:
8I5B08 / 8I5B15 / 8I5B16 / 8I5B25 / 8I5B26 / 8I5B40 / 8I5B41 / 8I5B50 / 8I5B51 / 8I5B80

Models ending in “FB” (e.g., 8I5B16, 8I5B26) typically refer to “Full Bore” variants or specific flange configurations tailored for distinct installation needs .

Detailed Ordering Code Breakdown: 8I5B15-AAIBAAAAFAAAAACAAAWAA1

To illustrate the customization potential, ST-YUKE CO., LIMITED provides a detailed of the order code for the 8I5B15 model. Understanding these features is crucial when specifying a flowmeter for a unique application.

Base Model: 8I5B15

8I5B: Coriolis flowmeter, remote version (sensor), Promass I series.

15: Nominal diameter DN15 (1/2″).

Breakdown of the Feature String: AAIBAAAAFAAAAACAAAWAA2

We can segment this long string into specific feature modules:

AA (Approval): Non-hazardous area / Standard.

I (Output; Display): Output ; 4-20 mA HART + terminal strip version ; display absent (for remote display via transmitter).

B (Housing; Sensor): Housing ; 316L (cast) ; compact housing (for remote version, this likely refers to the sensor junction box housing material).

A (Cable Entry): Cable gland M20 (thread).

A (Sensor; Advanced Features): This position often denotes sensor options; “A” typically signifies the standard version without special features.

A (Measuring Tube; Material; Pressure): Titanium (L pressure rating PN100/Cl.600/63K).

A (Calibration; Flow): Calibration; 0.1% ; 3-point calibration (oil/water).

F (Accessory; Sensor): Without extra accessory.

A (Approval; Sensor): Without special type examination.

A (Basic Spec; Sensor): Standard version.

A (Application): Standard version, suitable for general liquids and gases .

A (Ex ia; Sensor): Without Ex ia approval.

C (Cable Gland): Gland M20 (EEx e).

A (Special Inspection; Sensor): Without special inspection.

A (Medium Contact; Wetted Parts): Vitro seal (standard).

A (Basic Material; Process Connection): For example, standard material for the flange/connection.

W (Process Connection): Flange EN (DIN) PN40.

A (Connection Type; Size): DN15 (1/2″) flanges, aligning with the 8I5B15 base selection.

A (Surface; Roughness): Standard (not polished).

2 (Additional Test; Certificate): Declaration of conformity to EN10204-3.1 material certificate.

AA1 (Transmitter; Allocation): This trailing part allocates the specific Promass 500 transmitter (e.g., standard 4-20mA HART) to the sensor .

Note: While this is a representative breakdown based on standard E+H logic, actual configurations should always be verified with the official Endress+Hauser configuration tools. ST-YUKE CO., LIMITED can assist in validating these codes against your specific P&ID requirements.
