Series DMTFP Portable Transit Time Flow Meters are a state-of-the-art universal transit-time flow meter designed using Multibeam technology and low-voltage broadband pulse transmission, feature the worlds advanced non-invasive flow measurement technology providing a measuring system with unsurpassed accuracy, versatility, ease of installation and dependability. Although designed primarily for cleaner liquids, the flow meter can reliably measure liquids containing moderate amounts of suspended solids or aeration. DMTFP is designed for long- or short-term flow measurement surveys on full-pipe liquid systems and is ideal for verifying calibration of permanently mounted flow meters of all types.
The flow meter features a tactile keypad, 40-hour battery (rechargeable), back-lit graphics display C all integrated into a rugged, watertight enclosure.
The cost-effective and versatile DMTFP flow meter comes complete with all accessories necessary for measuring piping systems from 1" [25 mm] to 180".
Features:
· Cost effective and versatile.
· High accuracy, better than 1.0% read.
· Portable main unit, Compact enclosure. Portable case for all
accessories.
· Wide flow measurement range, from 0.03 to 105ft/s
(0.01m/s ~32 m/s).
· Velocity, volumetric and totalized flow display.
· Bi-directional. Totalizer for net, positive and negative flow display.
· Wide pipe size range , from 3/ 4" to 240" (DN 20~6,000mm).
· Suitable for all commonly used pipe materials.
· Rechargeable battery for 40 hours of operation.
· Self-explanatory user interface, easy to operate.
· Signal quality tracking and self-adjusting capabilities automatically match transducer to pipe material.
· Options:( Data Logger: 512M (200,000 event), 16-bit integral DB-9 RS232C Connection can be removed and installed without disconnecting system power.)
· Options:(Hart&ModBus Protocol Module.)
· Ideal for both clean and opaque liquid flow, in fact, most any
liquid containing less than 5% total suspended solids (TSS) or aeration.
· Clear, user-friendly menu selections make DMTFP simple and
convenient to use.
Applications:
The DMTFP flowmeter is ideal for flow surveys and closed Cpipe applications where non-invasive measurement of liquids is required .Benefited from our advanced digital signal processing technology, the handhold flowmeter works reliably in both clean and opaque liquid flow. Examples of applications include:
· Water, including hot water, chilled water, city water, sea water, etc.
· Sewage and drainage water with small particle quantity.
· Oil, including crude oil, lubricating oil, diesel oil ,fuel oil, etc.
· Chemicals, including alcohol, acids, etc.
· Solvents.
· Beverage and food processors.
· HVAC hot and cool water, water /glycol solutions.
· Water and waste treatment.
· Power plants (nuclear power plants, thermal & hydropower plants), heat energy boiler feed water.
· Energy consumption supervision and water conservation management.
· Metallurgy and miming applications (e.g., acid recovery).
· Marine operation and maintenance.
· Pulp and paper.
· Pipeline leak detection, inspection, tracking and collection.
· Energy measurement and balancing.
· Network monitoring.
