EMCO's model V-Bar™ flow meter is an insertion vortex shedding flow meter. The V-Bar™ flow meter provides significant cost savings for line sizes from 3 to 80" without compromising performance. With high-accuracy, microprocessor-based electronics, no moving parts, and rugged construction, the V-Bar™ flow meter gives you the benefits of over 35 years of practical experience. The V-Bar™ flow meter measures liquids or gases, including steam, for pipe sizes from 3 to 80".

Features


Unparalleled Performance
± 1.0% of rate accuracy for liquids ± 1.5% of rate accuracy for gas and steam ± 0.15% of rate repeatability Turndown ratio up to 25:1 FM and CSA approvals Calibration is traceable to NIST

Significant Cost Savings
One V-Bar™ flow meter is suitable for pipe sizes from 3 to 80", so there is one purchase price regardless of pipe size, resulting in typical savings of up to 80% for 24" lines and 50% for 10" lines compared to full-bore flow meters Installed quickly and easily, saving as much as 70% in labor installation costs when compared to full-bore flow meters Hot-tap-compatible installation allows removal without process shutdown; this not only avoids disruption of a critical process but also reduces labor costs No moving parts reduces maintenance costs Negligible pressure drop, typically 10 times less than an orifice plate, reduces energy and operating costs Optional integral pressure and temperature measurement enables mass flow measurement from one pipe tap (installation)

Ease of Operation
Factory calibrated and programmed for specific applications Start-up without any additional calibration or programming The local display alternates between flow rate and totalized flow Menu-driven EZ-Logic™ user interface enables local programming HART^® communication protocol

Installation Specifications
Tap Size		1.875" (47.6 mm) minimum diameter
Mounting		Install flow meter vertically, horizontally, or at any angle. The meter is attached perpendicular to the axis of the pipe and should not be mounted "upside-down" (with its top section hanging below the pipe mount). For liquid service, the flow line must be full during flowmeter operation. In vertical lines, flow direction should be upward for optimum flowmeter performance.
Straight run piping	(D = internal diameter of pipe)	Upstream	Downstream
	One 90° elbow before meter	10 D	5 D
	Two 90° elbows before meter	15 D	5 D
	Two 90° elbows out of plane before the meter	30 D	5 D
	Reduction before the meter	10 D	5 D
	Regulator or valve partially closed before the meter	30 D	5 D
Site selection		Select installation location to minimize turbulence and swirl. The piping configuration, i.e., valves, elbows, pumps, may add disturbances to the flow.
Hot-tap compatibility		The V-Bar-600/60S is hot-tap compatible, which means that the sensor can be installed and removed under full-flow conditions. The V-Bar-910/960 is hot-tap compatible when installed with a 2" double flanged, full- port ball or gate valve. The V-Bar-700 requires line shutdown and depressurization prior to installation.
