Product Overview
The JC-LG Series Orifice Plate is a primary flow measurement element designed for differential pressure flow measurement of liquids, gases and steam.
When fluid passes through the orifice, its velocity and pressure change, creating a differential pressure between the upstream and downstream sides. The flow rate can be calculated from this differential pressure together with the relevant process data and flow calculation parameters.
Manufactured from stainless steel, the orifice plate can be configured for different pipeline sizes, pressure ratings, pressure tapping methods and process conditions.
A compatible differential pressure transmitter and suitable flow calculation setup can be selected when required.
Applications
The JC-LG orifice plate can be used in differential pressure flow measurement systems for:
Key Features and Benefits
Differential Pressure Measurement
Uses the pressure difference generated across the orifice to support flow rate calculation.
Stainless Steel Construction
Available in SS304, SS316 or SS316L, subject to the selected configuration and process medium.
Wide Size Range
Nominal sizes from DN15 to DN1000 are listed as customizable options, subject to design and availability.
Multiple Pressure Tapping Options
Flange tap, corner tap and D-D/2 tap configurations can be selected according to the required design.
No Moving Parts
The orifice plate has no moving mechanical components, helping simplify routine maintenance.
Flexible Installation Options
Flange specifications and connection standards can be selected to match compatible pipeline designs.
Optional Measurement Accessories
A differential pressure transmitter and valve manifold can be specified separately or as part of a confirmed assembly.

Selection Guide
To select a suitable orifice plate, please provide:
Fluid: Liquid, gas or steam, including the medium name.
Flow Range: Minimum, normal and maximum flow rates.
Pipeline Size: Nominal diameter and actual pipe specifications.
Operating Conditions: Pressure and temperature.
Pressure Rating: Required flange standard and pressure rating.
Material: Required material based on fluid compatibility.
Pressure Tapping: Preferred tapping method, if specified.
Output and Accessories: Whether a differential pressure transmitter or valve manifold is required.
These details help determine the suitable orifice design and the parameters needed for flow calculation.
FAQ
Q1: What is an orifice plate used for?
It creates a differential pressure that can be used to calculate fluid flow rate.
Q2: Can it measure liquids, gases and steam?
Yes. The design must be selected for the specific medium and operating conditions.
Q3: Does the orifice plate include a transmitter?
Not necessarily. A differential pressure transmitter can be selected separately or included in a confirmed assembly.
Q4: Can the size and material be customized?
Yes. Size and material options depend on the required design and operating conditions.
Please provide the fluid, flow range, pipe size, pressure, temperature, material and quantity.
