FLC-FN-PIP
Flow nozzle FLC-FN-PIP
For in-pipe installation, for flange assembly

The design of the flow nozzle is based on Bernoulli's equation
and consists of a convergent section with a rounded profile and
a cylindrical throat. Due to its rigidity the flow nozzle is
dimensionally more stable at higher temperature and flow rate
than an orifice.

The flow nozzle is generally used for measuring the flow of steam
as well as non-viscous, erosive and high-velocity media. It can be
used in a wide variety of applications that include steam, air, water,
vapour, gas, chemical substances and high temperatures. For
applications with erosive media a hardened internal surface is available.

Suitable for liquid, gas and steam flow measurement
Optimum solution for measuring the flow of steam
Accuracy 0.1 % of actual flow rate
Repeatability of measurement 0.1 %
Lowest pressure loss in the family of primary flow elements

The differential pressure generated by the primary flow element is 
normally transformed into an electrical signal proportional to the 
flow rate by a differential pressure transmitter.
