List pricing on the OMEGA FPD3000 positive displacement flow meter series for fuels and oils runs $1,177.20 to $1,787.30 per unit as of 2026-07-25, with 1/4 in process connections and amplified square-wave electrical output across the family [S1].
The cost spread on those three catalog SKUs (FPD3002, FPD3003, FPD3004) tracks volumetric flow range more than connection size, since all three share the 1/4 in fitting, and minimum measurable rate climbs from 0.13 gal/h on FPD3002 to 4 gal/h on FPD3003 [S1].
Where the List Price Lands: Concrete 2026 Numbers
Three published OMEGA SKU prices anchor the low end of the small-line PD market: FPD3002 at $1,177.20 each (4 in stock), FPD3003 at $1,236.58 each (5-week lead time), and FPD3004 at $1,787.30 each [S1]. The jump from FPD3002 to FPD3004 is a 51.8% premium, almost entirely from a wider calibrated flow window, not a different wetted material or protocol stack [S1].
For comparison, the Burkert Type 8072 oval-gear PD meter (a glue, honey, and oil service unit with 4-20 mA loop-powered switching) has been discontinued and is no longer available as of 2026-07-31, with the OEM directing buyers to a successor consultation [S2]. That obsolescence event matters: a published list price of zero, plus a quoted successor, is a real procurement risk for plants still standardising on the 8072 platform [S2].
What Drives the Price Up or Down
Four variables move the number on a PD meter quote: wetted material and pressure rating, line size, electronics protocol stack, and hazardous-area certification. A 1/4 in brass-bodied, square-wave output meter is the floor, around $1,177.20 in the OMEGA FPD3000 family [S1].
The published engineering rule of thumb is that PD is the only technology that directly measures volume rather than inferring it from velocity or mass, which is why its accuracy class (often ±0.5% of reading, better than turbine or paddle wheel) carries a price premium over inferred meters at the same line size [S4]. Higher viscosities, for which PD is the default choice, also push the meter into a heavier rotor and bearing package, again lifting the list price [S4].
PD vs Other Flow Technologies: A Cost-Aware Comparison
PD meters are typically priced above turbine, paddle wheel, and vortex meters at the same line size, but below Coriolis meters, which generally start higher for the same line class [S4]. The trade-off matrix for a buyer looks like this: PD wins on accuracy for clean, viscous, or lubricating fluids (oils, fuels, polymers, adhesives) at the cost of moving parts that need a clean, filtered stream [S4]. Coriolis wins on mass accuracy and multi-variable output, but at a 2-4x price multiplier and a non-trivial pressure drop [S4]. Electromagnetic meters are price-competitive on conductive clean liquids but useless for hydrocarbons and oils, the exact service window where PD lives [S4].
Buyers comparing vortex and PD for steam or hydrocarbon batching should note that vortex loses linearity in low-Reynolds laminar regimes where PD keeps reading accurately; that same operating regime is what justifies the higher PD price tag [S4]. For a deeper look at vortex pricing and its 2026 surcharge stack, see the vortex flowmeter price and cost guide.
Selection Criteria: When PD Is the Right Buy, and When It Is Not
PD is the right pick for batching, custody transfer, and additive injection of clean, viscous, or lubricating fluids where ±0.5% or better of-reading accuracy is required and the stream is filtered to remove particulates that would score the rotors or pistons [S4]. It is the wrong pick for slurries, untreated wastewater, or any stream with entrained gas, where the rotors can gas-lock and the reading becomes meaningless [S4].
Buyers writing a flow specification should pin down: fluid type, minimum and maximum flow, accuracy target, fluid temperature and viscosity, wetted-material compatibility, maximum line pressure, allowable pressure drop, hazardous-area classification, and output protocol, before pricing [S4]. Skipping any one of these and the quote comes back with caveats. For a structured look at how Reynolds number, steam, and output selection shape the vortex decision, see the vortex flow meter selection guide.
Total Cost of Ownership, Not Just Sticker Price
Purchase price is roughly 40-60% of the lifetime cost of an installed PD meter; the rest is installation (strainers, bypass piping, air eliminators), calibration (a typical lab re-cal is $300-800 every 12-24 months depending on accuracy class), and unplanned maintenance when particulates score the rotors (qualitative, from standard PD service patterns). The OMEGA FPD3000 line at 1/4 in is small enough to ship 4 in stock, but the FPD3003 carries a 5-week factory lead, which itself is a hidden cost when a process is down [S1].
For buyers cross-shopping against mass-flow or thermal technologies, the relevant comparison metric is dollars per percent of accuracy per inch of line size, not sticker alone. A PD meter at $1,236.58 with ±0.5% accuracy on 1/4 in lines wins on accuracy-per-dollar for oil service; a thermal mass meter at similar line size usually costs more and adds gas-only service constraints [S1][S4]. For gas-duty applications, see the thermal mass flow meter selection guide.
Lead Time, Availability, and EOL Risk in 2026
Availability is now a first-class cost driver. The OMEGA FPD3002 is in stock at 4 units, the FPD3003 carries a 5-week lead, and the FPD3004 ships on order [S1]. On the Burkert side, the Type 8072 has been formally retired as of 2026-07-31, with no direct successor SKU published; buyers holding spares should treat that as a 90-day-to-obsolescence risk on any new project standardising on 8072 [S2].
For an industrial procurement team, the practical signal is to lock the second-source SKU at the same time as the first-source PO, and to verify hazardous-area certification documentation (IECEx, ATEX) before signing the PO rather than after delivery, since certification paperwork is the most common source of late-project cost overruns on PD meter packages.
