Portable Ultrasonic Flowmeter Kit

Series PUB Portable Ultrasonic Flowmeter Kit

Portable and Non-Invasive

The Series PUB & PUF Portable Ultrasonic Flowmeter Kits utilize the transit-time difference for measuring flow rates in pipes non-invasively. They are compact and lightweight instruments incorporating the latest electronics and signal processing technologies, realizing high performance and easy operation. These devices are perfect for on-the-go flow monitoring, capable of 20 hours continuous operation with built-in, rechargeable battery. The PUB comes with a rugged carrying case with molded foam inserts while the PUF boasts an IP67 rated case to hold and protect all equipment conveniently. Their screens offer easy to read text with convenient backlight for visual comfort. The efficient layout of the function keys adds to these units easy to use programming. These series offer analog as well as a pulsed outputs.

PRINCIPLES OF OPERATION

Two sensors are placed on the exterior of the pipe, and each transmits an ultrasonic pulse through the pipe and fluid to the other. The velocity of the liquid flowing through the pipes causes the pulse to accelerate or decelerate. The difference in the transit times of the two pulses is used to calculate the flow rate. The use of transit time allows the flowmeter to be unaffected by pressure or temperature changes.

Orifice Plate Flowmeter

Series OP Orifice Plate Flowmeter

The Series OP Orifice Plate Flowmeter is a complete orifice plate flow metering package. It incorporates a stainless steel orifice plate with a unique holder or carrier ring containing metering taps and integral gaskets. It was designed for use wherever there is an application for a conventional flow orifice plate. It can also be used in place of other primary differential producers for efficiency and cost effectiveness. Installation is accomplished simply by slipping the unit between standard flanges (orifice flanges are not required). The Series OP is available in line sizes from 1/2" to 24" and can be used with compatible liquids and gases.

Features:

• Mounted with standard flanges
• Standard "corner tap" configuration
• Corrosion free material
• Simplified installation
• Built in metering taps (1/4" female NPT STD)
• Proven through a wide range of applications for accuracy and energy efficiency
• Assures long term reliability and accuracy
• Service : Compatible liquids and gases.
• Installation : Standard flange 125/150 rating.
• Pipe Requirements : General requirements 10 diameter upstream and 5 diameter downstream.

Applications:

• Fluid flow rates in building water lines
• Boiler feedwater
• Cooling water
• Combustion or compressed air
• Steam flow

Accuracy:

The Series OP utilizes the corner tap proportions as defined in ISO 5167. While this code may not be referred to as International Standard until accepted by the ISO Council, the ASME Fluid Meters Research Committee has suggested that the dimensionless coefficient equation developed by the International Standards Organization (ISO) and presented in ISO 5167 is significantly better for the broad spectrum of flow measurement applications throughout process industries.

The coefficient values used in the Series OP bore calculations represent the same confidence level assigned to the flange and radius taps widely accepted in fluid flow measurement.

The accuracy assigned to the coefficient values is 0.6% full scale flow for d/D (Beta) values 0.2 to 0.6 and 0.7% for Beta values 0.7 to 0.75 (i.e. of 0.7 would have an uncertainty value of 0.7% full scale flow).

Accuracy of the differential signal produced by the Series OP equals or exceeds that of a properly manufactured and installed flange or radius tap orifice meter.

Mounting:

The orifice metering primary shall be suitable for installation between standard ANSI 125/150# flanges (any material) mounted on standard pipe (any material). The unit shall be "self centering" within the bolt circle of the flanges. No alignment of the orifice shall be necessary unless used with 300# or non-standard flange ratings. Drilling and or tapping of the main or flanges will not be allowed or required. The overall laying length shall be 1.25 ?? including pre-attached ring type 1/8 ?? thick Buna "N" Gaskets.

Pipe Requirements:

Upstream and downstream pipe requirements are contingent upon two factors: (a) Beta Ratio-ratio of the orifice bore to the pipe I.D. (d/D); (b) The type of fitting or disturbance upstream of the Series OP. For most applications, 10 pipe dia. upstream & 5 dia. downstream are sufficient. (5 pipe dia. up and 2 dia. down are acceptable for non-critical application.)

compact ultrasonic flowmeter

model ufm compact ultrasonic flowmeter

cost effective, compact & adjustable design, non-invasive

model ufm compact ultrasonic flowmeter is a low cost clamp-on, ultrasonic flowmeter.the model ufm implements the transit-time difference to measure flow rates in pipes non-invasively. It is a compact and lightweight design, featuring an easily installed, all in one clamp-on unit. This unit can measure velocity and flow in pipes with outside diameters ranging from 0.98 to 4.62" (24.89 to 117.35 mm). The screen offers easy to read text with a convenient backlight for visual comfort.this model comes with a volume pulse and 4 to 20 ma flow rate output.

principles of operation

two sensors located in the guiderail are placed on the exterior of the pipe, and each transmits an ultrasonic pulse through the pipe and fluid to the other. The velocity of the liquid flowing through the pipes causes the pulse to accelerate or decelerate. The difference in the transit times of the two pulses is used to calculate the flow rate. The use of transit time allows the flowmeter to be unaffected by pressure or temperature changes.
