Choose Product Page by Pipe Size
Pipe size is the entry point. DN15-DN65 goes to the rotary-vane route, DN80-DN300 goes to the removable Woltman route, and DN80-DN200 is an overlap where vertical installation should switch the buyer to the vertical Woltman route.
For DN15-DN65 projects, the confirmed route is the rotary-vane water meter page.
Primary problem solved
Rotary-Vane Water Meter
Solves the small-pipe metering problem: common household, apartment and commercial branch lines need a compact meter body, clear reading and DN coverage from DN15 to DN65.
For DN80-DN300 projects, the confirmed main route is the removable Woltman water meter page.
Primary problem solved
Removable Woltman Water Meter
Solves the large-pipe service problem: bulk lines need flanged large-flow metering, and the removable structure makes future service easier than replacing the full meter body.
For DN80-DN200 vertical projects, use the vertical Woltman water meter page instead of the standard removable route.
Primary problem solved
Vertical Woltman Water Meter
Solves the installation-direction problem: when the pipe room or pipeline is vertical, the buyer needs a meter structure built for vertical installation rather than a standard horizontal layout.
These three routes are the product-page structure to use for customer selection. The goal is to move buyers from DN question to the correct product page quickly.

FAQ
How do I choose the right product page by DN?
Use DN15-DN65 for the rotary-vane water meter page, DN80-DN300 for the removable Woltman water meter page, and DN80-DN200 for the vertical Woltman water meter page when the installation direction is vertical.
When should I choose the removable Woltman route?
Choose the removable Woltman route for DN80-DN300 bulk lines when maintenance access, future service and large-flow measurement are important to the project.
When should I choose the vertical Woltman route?
Choose the vertical Woltman route for DN80-DN200 projects where the pipe room or pipeline direction requires vertical installation.
Can DN80-DN200 use both removable and vertical Woltman pages?
Yes. DN80-DN200 overlaps both routes. Use removable Woltman for standard large-pipe metering and easier maintenance; use vertical Woltman when installation direction is the deciding constraint.
Can you provide dimensions and installation drawings?
Yes. Send DN size, connection standard, pressure requirement and installation layout, and Chenshuo can provide model-specific dimensions or drawings subject to the selected meter configuration.
What information is required for a project quotation?
Send the pipe size, operating flow and connection requirement. Chenshuo can support model matching, datasheets, installation dimensions and quotation review for your project.
Share DN size, quantity, installation direction and project type.
Confirm thread or flange standard, pressure requirement, pulse output and drawing needs.
Receive model matching support before the final quotation is prepared.
