Page 6: Introduction
Theory of Operation The Preso Gemini Cone meter creates a differential pressure that is proportional to the rate fluid flow A transmitter measures the differential pressure and outputs an integrated electronic signal, typically via Modbus or a 4…20 mA output, to a flow... -

Preso Gemini Cone meters are differential pressure flow devices providing highly accurate and repeatable measurements of liquids, gases and steam The meter design provides longer lasting accuracy and lower permanent pressure loss than orifice... -
Page 8: Straight Pipe Run Requirements
Straight Pipe Run Requirements STOAIGHT PIPE OUN OEQUIOEMENTS With most flow elements, proper operation and performance is dependent on the required lengths of unrestricted upstream and downstream piping One of the advantages of the Gemini Cone meter is that a fully developed symmetrical flow profile is achieved with relatively short upstream and downstream lengths, so it needs minimal if any upstream and downstream straight pipe runs We recommend that the Gemini Cone meter be installed with zero to five pipe diameters and zero to three pipe diameters downstream... -

Page 11: Line Installation
Straight Pipe Run Requirements Line Installation All flanged Gemini Cone meters require a gasket between the flange on the process line and the mating flange on the meter itself Select gaskets that match the pressure and temperature ratings of the Gemini Cone flanges and resist corrosive properties of the process fluid Before completing the bolting process, make sure that the gaskets are properly centered so that protrusion into the pipe opening is minimized Misalignment may cause added flow turbulence which can affect meter performance, although... -

Page 14: Vertical Meter Installation
Meter Installation for Liquid Service Vertical Meter Installation In most process applications, some level of gas or vapor exists in a liquid service, even if the liquid is water As a result, the piping configuration must be designed so gas can rise back into the flow stream The process piping should be extended horizontally a very short distance from the downstream tap and then sloped at a nominal 1:12 angle to the top of the manifold block Mount the manifold block horizontally below the upstream tap so that piping from the upstream tap to the manifold slopes downward also... -

Meter Installation for Gas Service Vertical Meter Installation When installing the meter in a vertical position, make sure that no trap forms in the downstream tap such that gas is trapped in a liquid or liquid is trapped in a gas When measuring dry, non-condensing gases, where there is absolutely no risk for liquid being present, extend the piping from the downstream pressure tap of the cone meter horizontally and then angle it upward to connect to the manifold block Mount the manifold block horizontally Slope the tubing from the upstream tap of the cone meter 1 in /ft to the same level as... -
Page 17: Meter Installation For Steam Service
Meter Installation for Steam Service METEO INSTALLATION FOO STEAM SEOVICE Steam measurement is one of the most difficult applications for differential pressure transmitter tubing and requires careful consideration during installation Steam is usually at a high temperature, which will damage the transmitter In addition, steam can vary between liquid or gaseous phase depending on temperature and pressure Due to this, the differential pressure impulse tubing must be oriented in such a manner that it can operate with gas liquid, or a combination of the two present... - Page 18 Meter Installation for Steam Service Filling Crosses (Fill with water to same level) HI LO Flow By-pass Valve DP Transmitter or Direct Read Gage Side View Front View Figure 8: Typical horizontal installation for steam Filling Crosses (Fill with water to same level) HI LO Flow By-pass...

Meter Installation for Steam Service Vertical Meter Installation For steam service installations in which the meter is oriented vertically, extend the piping from the upstream pressure tap horizontally to a T-connector The T-connector enables a plug to be installed at the top for liquid filling purposes to avoid overheating of the differential pressure cell Position the manifold block directly below, at a distance that keeps the steam at a safe operating temperature when it reaches the differential pressure transmitter Extend both lines to the T-connectors NOTE:... -

System Modifications SYSTEM MODIFICATIONS Square Ooot Error Differential pressure measurement is only accurate for steady-state flow Flow pulsation caused by reciprocating compressors, defective regulators, and like equipment can cause mis-registration of delivered volumes Significant errors occur when using differential pressure devices at the discharge of a reciprocating gas compressor where pressure pulses may exceed 10% of static pressure This causes a condition called square root error, which may be reduced by the use of an acoustic filter Gauge Line Error... -
