PDFlo Positive Displacement Flow Meters for Industrial Service
PDFlo positive displacement flow meters are affordable and accurate. One primary feature is their ability to maintain consistent accuracy despite changing viscosity conditions. This reliability, coupled with a large turndown range, offers an affordable replacement for older turbine technology. The meter's solid construction and excellent dynamic response are well suited to the measurement of oil, grease, fuel, solvents, polyurethanes, brake fluid, Skydrol as well as other nonabrasive lubricating fluids.

The GearFlo™ Helical Gear Flow Meter is constructed of two highly accurate cycloid shaped screw spindles that mesh and rotate inside the cylindrical housing with two overlapping holes in the form of a figure 8, forming the measuring chamber. Its lower pressure drop makes this meter perfect for measuring polyurethanes and polymer, glues and sealing materials and heavy fuel oils. |

The GearFlo™ PDTX4 is a four-wire, meter mounted digital flow transmitter that is compatible with most PDFlo flow meters. The PDTX4 is housed in a Class I Hazardous Location rated enclosure and features HART communication protocol. A large, back-lighted LCD graphic display provides an easy to read indication of flow rate or total in user programmable engineering units. To change any key functions, simply use the magnet that is attached. No opening of the enclosure is required. To prevent the magnet from entering the programming mode inadvertently, an on board jumper controls ability to allow programming via external magnet. An isolated input also allows for remote rest of the totalizer. A 4-20 mA rate output with user programmable filtering and scaling is also provided for remote indication. |
Power Requirement: 15-24 VDC/150mA (customer supplied) |

The GearFlo™ PDTX2 is a two-wire, meter mounted flow transmitter that is compatible with most PDFlo flow meters. The PDTX2 is used in a wide variety of applications where ease of operation and flexibility are required. A NEMA 4X enclosure houses a large 6-digit LCD display screen where either flow rate or total is continuously displayed in the customers selected and programmed engineering units. The selection of rate, total, reset of the total, programmable sleep mode and the real-time clock can be done via magnet-without opening the enclosure. A long life field replaceable battery provides power for a period of 4 years - depending on the units configuration. |
Power: Internal 3.6V "C" Cell Battery |
