Venturi Flowmeter with Magnehelic Gage

Series VFLO Venturi Flowmeter with Magnehelic Gage

2.5% Accuracy, Dual Scale in SCFM & in w.c.

The Series VFLO Venturi Flowmeter with Magnehelic Gage is fabricated from aluminum and has a gradual Venturi profile to reduce pressure losses through the meter. Flowmeter can be used in a vertical or horizontal position just by rotating the Magnehelic gage. The Magnehelic gage provides a large, clear and accurate display of your differential pressure reading. Each meter is calibrated at standard atmospheric conditions. The dual scale reads in SCFM and in w.c. The meter is supplied with easy to read reference charts for various flow conditions. It is available in line sizes from 1" to 4" and can handle vacuum and pressure applications.

To place an order for the Venturi Flowmeter with Magnehelic Gage, see the Magnehelic Configurator.

Series AVU Air Velocity Transmitter

ideal for building automation systems, 5% or 8% full scale accuracy

the seris avu air velocity transmitter is ideal for a wide range of hvac measurement and control applications, particularly in complete building control and energy management systems. The series avu transmitter operates by measuring the heat loss from one of the two sensing elements in the air stream, then calculating the air velocity. Units are virtually immune to drift due to the design of the sensing element, which makes the transmitter accurate over the whole air velocity range.

calibration option available under accessories.

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.)

Type : Orifice Plate Flowmeter

Material : Buna-N Gaskets.

Accuracy : 0.6% Full Scale Flow. (Beta= .2-.6) 0.7% For Beta Greater Than .6.

Application : Compatible Liquids And Gases.

Bar Graph Meter (Series BGM)

series bgm bar graph meter

clear relative position and high resolution in one

the series bgm digital bar graph meter is extremely durable and can replace a wide range of analog meters. The 4-digit display will significantly reduce the potential for human error in reading by eliminating errors commonly produced by the viewing angle when reading analog meters. This series has a key pad that allows for easy access of features without complex menu structures. With the combined ability to create a wide range of custom faceplate and the optional nema 4x bezel, the series bgm can be used in a variety of applications. The led bar graph adds a visual indicator of the measured value so that it can be visually analyzed, preventing accidents or system failures from happening.
