Feature:

•  High accuracy; ± 0.5 % of full range. 
•  Excellent repeatability, repeatability in a short time can reach to 0.05%~0.2%, Because of excellent repeatability, customers can have extremely high accuracy if they often calibrate or calibrate on-line. 
•  Output with pulse frequency signal, suitable total flow measuring and computer connection.
•  No zero drift and strong ability in anti-noise.
•  Can acquire very high frequency signal (3~4 KHz), strong signal resolution.
•  Wide range: middle and large diameter can reach to 1:20, small diameter can reach 1:10.
•  Compact and light structure, convenience in installation and maintenance, ability of large flow. 
•  Suitable to measure in high pressure .No need to open aperture on the meter, so it is easy to make high pressure meter.
•  Many models of dedicated sensors. Can design dedicated sensors of special requirements for customer, such as low temperature type, two-way type, pump type, sand specific type.
•  Can make plug-in type, suitable to large diameter measuring, little pressure loss, low price, can get out without flow cut off. Convenient in installing and maintaining. 
•  Stainless housing of signal converter

Petrotech Orifice Plates are the most commonly used differential pressure measurement device and are applicable for measurements in gases, clean liquids, and low velocity steam. Orifice plates allow for relatively easy installation and replacement if necessitated by changes in process parameters or life cycle deterioration.

Product Details:

The Daniel Senior Orifice Meter is a dual-chamber device that reigns as the most widely used means of measurement for natural gas. The Senior Orifice Fitting permits plate-changing under flowing conditions, which translates into no operation shutdown.Since its original development, the Senior Orifice Fitting product line has grown enormously to serve customers with applications for pipeline sizes from 2 inches to 48 inches, and pressure ratings up to 10,000 pounds per square inch. In addition, the use of corrosion resistant and other special materials makes this product suitable for sour gas service and other special applications. Daniel's most popular Senior Orifice Fitting, the "Flangnek®," has a weldneck inlet and a flanged outlet. Daniel fittings meet or exceed API Chapter 14, Section 3, Part 2 (14.3/AGA 3) requirements.Simplex Orifice Plate Holders:Daniel Simplex Orifice Plate Holders are single-chamber fittings that house and accurately position an orifice plate for differential pressure measurement. These fittings allow the removal or insertion of the orifice plate quickly and economically. The single chamber design allows for inspection and replacement of orifice plates without removing the Simplex meter from the flow line. Since Simplex fittings use one piece bodies, there is no spillage in liquid service, no rusted stud bolts, no nuts to remove, no flanges to spread apart and no line strain. The Simplex is designed and manufactured in strict accordance with all applicable ANSI, ASTM, API 14.3 and ISO 5167 specifications.
