Product catalog summary

Overview: This document is a datasheet for domestic water meters, specifically models M-NR, M-NSR, and M-NFR, which are designed for different installation scenarios and specifications. The datasheet provides detailed technical specifications, features, and ordering information for these models.

Applications:

M-NR Model 101: Suitable for horizontal installation with nominal diameters ranging from DN 15 to 50 mm. It operates under a pressure of PN 16 and is designed for cold water up to 30°C, with a safety margin up to 50°C.
M-NSR Model 102: Designed for installation in rising pipes with nominal diameters from DN 20 to 40 mm. It follows DIN 19648 Part 3 standards and operates under similar conditions as Model 101.
M-NFR Model 103: Intended for downpipe installations, also with nominal diameters from DN 20 to 40 mm, adhering to DIN ISO 4064 and DIN 19648 Part 3 standards.

Features:

Low head loss and extended measuring range.
Records minimal water consumption and withstands short-term loads.
Corrosion-resistant with maximum long-term accuracy.
Includes forward and return metering, fine adjustment via regulating cocks, and a strainer insert for easy cleaning.

Technical Data:

Model 101: Available in various nominal diameters with flow rates ranging from 1.5 to 15 m3/h. It features different coupling threads and overall lengths, with weights varying based on configuration.
Model 102 and 103: Similar specifications to Model 101, with variations in nominal diameters and flow rates. They also offer different coupling threads and dimensions.

Graphs:

Error and head loss graphs are provided for each model, illustrating performance across different flow rates.

Ordering Information:

Detailed order references are provided for each model, specifying nominal flow rates, diameters, connection types, and article numbers.

Notes:

Calibration and installation recommendations are included, emphasizing the importance of flushing pipes before meter installation.
Special versions and materials are available upon request.
