OriMaster FPD500 Compact orifice flowmeter OriMaster – the one-piece DP flowmeter Benefits OriMaster is a stand-alone orifice-based flowmeter with a difference – its advanced design greatly simplifies installation and commissioning. OriMaster incorporates the following features: — A wafer-bodied orifice carrier assembly with integral square-edged, concentric plate and corner tapping points — Integral 3-valve manifold (optional 5-valve manifold available) — Integral direct connections between the carrier tappings and manifold — DP transmitter, factory-mounted onto the manifold and...

Basic principle of operation DP devices work on a principle based upon the Law of Conservation of Energy, where a restriction in the fluid path causes an acceleration in the fluid velocity with a corresponding increase in kinetic energy. The gain in kinetic energy is at the expense of pressure energy, resulting in a drop in fluid pressure across the narrowest part of the restriction. The drop in pressure and the flow rate are linked by the following (simplified) relationship: Q = k DP where Q = fluid flow rate k = a constant for that DP device The Vena Contracta increases the velocity...

OriMaster FPD500 Compact orifice flowmeter Versions OriMaster is available in two versions: OriMaster V – a compact flowmeter for general purpose measurement in volumetric units (actual volume). OriMaster V uses the ABB 364 or 266 DP transmitter to provide a flow rate and total display and a 4 to 20 mA output proportional to the actual volume flowrate. The transmitter case and meter body are all in stainless steel as standard when the 364 transmitter is fitted. 316 stainless steel transmitter cases are also available. There are 5 DP sensor ranges available. For optimum accuracy select the...

OriMaster M – a compact flowmeter, providing measurement directly in mass units for liquids and steam. Gas flow is measured directly in reduced volume units. OriMaster M uses the ABB 267 multivariable transmitter to measure DP, temperature and pressure, providing a flowrate display and a 4 to 20 mA output proportional to the mass or corrected volume flowrate. The body is stainless steel and the case is alloy (stainless steel optional). An optional internal temperature element is available. There are 3 DP sensor ranges available. For optimum accuracy select the sensor so that the full scale...
