Network Meter Block Installation, Operation, & Maintenance Manual
Introduction 1
1 Introduction
This manual provides guidance for the installation, operation, and maintenance of the Smith Meter
Networked Meter Block (NMB). When installed following the guidelines contained in this manual, the NMB
should provide many years of safe, accurate, and reliable use.
1.1 Product Description
The NMB is a Ethernet network-enabled field input/output (I/O) device with the ability to connect peripheral
devices to standard industrial infrastructure, especially cloud applications. It also is capable of local control,
such as basic logic and closed loop algorithms. For example, it can communicate a meter’s flow rate and
additional data through open communication protocols. Users can access the meter data remotely over the
network in near real-time and communicate back to the NMB using common tools, such as a Web browser.
The NMB makes it possible to eliminate much of the expense of today's multi-layered hardware
infrastructures and specialized tools, reducing the overall cost to achieve total system integration.
Additionally, NMB models with Turbine Meter Diagnostic firmware—developed specifically for liquid turbine
meters—ensures the accuracy of measurements by detecting potential issues as they occur in real time.
1.1.1 NMB Models
Several models of the NMB are available, with a unique model code identifying each variant, such as
NMB-XP-TMD-06. The following table provides details about the available options for your NMB and its
model codes:
Additionally, the DIN rail mounting kit—designed to be used for a single panel-mounted NMB—also may
be purchased with your NMB.
These models represent standalone versions of the NMB and are designed to be used for retrofit
applications. You also may order the NMB as a factory-installed accessory when purchasing any of
TechnipFMC’s turbine or positive displacement (PD) meters.
