Project Location: Tanzania, East Africa
Product: Endress+Hauser Prowirl D 200 Vortex Flowmeter
Model: 7D2C1H-23V8/0
Extended Order Code: 7D2C1H-AABCCAAAAAD2SKA1+LA
Nominal Diameter: DN100 (4 inches)
Quantity: 1 Unit
Project Type: Discontinued Flowmeter Replacement and Instrument Supply
Supplier: Dalian Zero Instrument Technology Co., Ltd.
1. Project Background
An industrial instrumentation customer in Tanzania required a replacement for an existing Endress+Hauser vortex flowmeter.
The original instrument model was no longer available for ordering, creating a challenge for the customer’s procurement process.
Rather than selecting an unrelated alternative, the customer preferred to continue using Endress+Hauser equipment to maintain consistency with the existing instrumentation system.
Zero Instrument was contacted to identify a suitable replacement, confirm the ordering configuration, and coordinate the supply of the required flowmeter.
2. Customer Requirements
The customer’s primary requirements included:
Replacement of the discontinued Endress+Hauser flowmeter
Original Endress+Hauser equipment
DN100 (4-inch) nominal diameter
Suitable configuration for the existing process application
4–20 mA HART communication
Correct order-code identification
Reliable international procurement and delivery support
The project required careful attention to the product configuration because replacing an older industrial flowmeter involves more than matching the nominal pipe diameter.
Mechanical installation requirements, electrical connections, measurement functions, and process conditions must also be considered.
3. Original Instrument and Replacement Selection
Following a review of the original inquiry, the discontinued instrument was identified as:
Original Model: 7D2B1H series
Product Family: Endress+Hauser Prowirl
Status: Discontinued
The selected replacement was:
Replacement Product: Endress+Hauser Prowirl D 200
Order Code: 7D2C1H-23V8/0
Extended Order Code: 7D2C1H-AABCCAAAAAD2SKA1+LA
Nominal Diameter: DN100 (4″)
The replacement belongs to the Endress+Hauser Prowirl D 200 series, a vortex flowmeter platform designed for industrial flow measurement applications.
The selected configuration was submitted for procurement according to the customer’s replacement requirements.
4. Technical Overview of the Prowirl D 200
Vortex Flow Measurement Principle
The Prowirl D 200 operates using the vortex shedding principle.
When fluid flows past a bluff body inside the meter, vortices are generated alternately downstream. Their shedding frequency is related to the fluid velocity, allowing the instrument to determine volumetric flow.
This measurement principle is widely used for industrial applications involving steam, gases, and suitable liquids.
Wafer-Type Construction
The Prowirl D 200 series features a compact wafer-style design intended for installation between compatible pipe flanges.
This configuration provides a space-efficient solution for industrial piping systems.
Industrial Communication
The supplied unit’s packaging identifies the output as:
4–20 mA HART
This allows the instrument to communicate measurement information to compatible industrial control and monitoring systems.
Device Identification and Traceability
The instrument was supplied with its Endress+Hauser order code and individual serial identification.
These details allow the equipment to be identified and its documentation to be referenced through the manufacturer’s device information system.
5. Procurement and Order Coordination
Zero Instrument supported the customer through the procurement process, including:
Reviewing the original discontinued model
Identifying the current Prowirl D 200 replacement
Confirming the new ordering code
Preparing the commercial quotation
Coordinating the Endress+Hauser purchase order
Following up on production and delivery progress
Verifying the completed instrument’s identification information
The order was processed with an estimated lead time of approximately eight weeks.
During the procurement process, the customer received updates on the progress of the order.
6. Product Completion and Packaging Verification
After the instrument was completed, warehouse photographs were obtained showing the original Endress+Hauser packaging label.
The packaging confirmed the following information:
Manufacturer: Endress+Hauser
Product: Prowirl D 200
Model: 7D2C1H
Order Code: 7D2C1H-23V8/0
Extended Order Code: 7D2C1H-AABCCAAAAAD2SKA1+LA
Nominal Diameter: DN100
Output: 4–20 mA HART
Country of Origin: China
The label also displayed the individual serial number, manufacturing order references, and handling instructions.
The completed instrument was prepared for the next stage of shipment coordination.
7. Project Outcome
The procurement and production stage was successfully completed.
Zero Instrument supplied the specified Endress+Hauser Prowirl D 200 replacement model and verified its identification against the confirmed order.
The project demonstrates the importance of accurate order-code identification when sourcing replacement instrumentation for discontinued industrial equipment.
By coordinating product selection, procurement, production follow-up, and documentation, Zero Instrument supported the customer’s replacement project without requiring the customer to independently manage the manufacturer’s ordering process.
Final installation and commissioning performance were not part of the documented supply-stage results.
8. Key Takeaways
This project highlights several important considerations when replacing discontinued vortex flowmeters.
Correct model identification: Original and extended order codes are essential for selecting the intended replacement.
Configuration verification: Nominal diameter alone does not establish complete interchangeability. Mechanical, electrical, and process specifications must also be reviewed.
Manufacturer traceability: Serial numbers and original packaging labels provide useful documentation for procurement records.
Reliable procurement coordination: Consistent communication throughout the ordering process helps customers plan equipment replacement and maintenance activities.
Conclusion
The successful completion of this Endress+Hauser Prowirl D 200 order demonstrates Zero Instrument’s experience in sourcing and supplying industrial measurement equipment for international customers.
For discontinued Endress+Hauser vortex flowmeters, accurate replacement selection and order-code verification are critical to reducing procurement uncertainty.
Zero Instrument supports customers worldwide with industrial flow measurement equipment, replacement model identification, technical coordination, and international supply services.
