Displacement Meter - Overview
provide exceptionally accurate service when using Liquid
Controls' unique positive displacement metering principle,
even under variable operating conditions (changes in
temperature, pressure and viscosity). Provides the energy
efficient and functional performance desired from an
economical volumetric measuring instrument. Available with
traditional mechanical seal or glandless magnetic driven
pulse output device.
accuracy and repeatability
maintenance, no metal-to-metal contact in measuring
pressure loss, a true gravity flow meter
of aluminum, cast iron, brass and stainless steel
materials of construction
operation without electrical power or signal
conditioning (for units equipped with mechanical
registers, printers or presets); no special piping
output and registration equipment where enhanced
accuracy and electronic communications are needed
& Measures approval (world-wide) for custody
transfer with mechanical or electronic registration
systems meeting API standards
accessories designed and approved to Class 1 Div. 2
metering refined petroleum products such as leaded and unleaded
gasoline, fuels oils, diesel fuel, kerosene, ethylene glycol
(antifreeze) and propylene glycol at rated capacity. Also
used on motor oils and rotogravure ink at reduced rates of flow.
metering aviation gasolines and jet fuels when meter is installed
downstream of the filter/separator. Non-ferrous
construction...meters may be operated at rated capacity.
metering a wide variety of products such as: liquid sugars, corn
syrup, corn sweeteners, dextrose, fructose, sucrose, maltose,
lactose, corn oil, soy bean oil, cotton seed oil, coconut oil, and
shortening's etc. Rate of flow is based on viscosity to
pressure loss relationship.
metering treated waters (deionized, demineralized, and potable)
and certain solvents where no red metals are allowed. Meters
may be operated at rated capacity, except for continuous duty
service. Note: Substitute for former class 6 and 17
applications. Anodized aluminum and stainless steel
metering chlorinated solvents such as: perchloroethylene,
trichloroethylene, trichloroethane, and methylene chloride.
Also used for general solvent service. Meters may be
operated at rated capacity, except for continuous duty service.
All ferrous construction.
metering acid pH liquids such as: nitric, phosphoric and glacial
acetic acids, amines citric (fruit juices) and vinegars. All
316 stainless steel construction. Operation at up to 80% of
maximum rated capacity is recommended.
metering liquified petroleum gas (LPG) including butane, isobutane,
pentane, ethane, freons and propane. Note: materials of
construction (including seals) are UL approved for propane,
modifications to materials of construction may be required for
other liquids listed, including commercial grade NH3.
metering crude oil (LACT and NOD). Also for heated and/or viscous
liquids including animal fats, resins, #6 oil and non-abrasive
asphalt emulsions. Rate of flow based on viscosity to
pressure loss relationship. Note: Substitute for former
class 5 applications.
metering oil or water based latex products, polyester resins, and
adhesives (neutral pH). Also available for metering
herbicides and nitrogen fertilizer solutions (requires viton and
teflon seals). Operation at 80% of rated capacity or less is
recommended. Shear sensitive liquids must be operated at 1/3
of rated capacity or less.
general solvent metering service such as: methanol, toluene,
xylene, naphtha, acetone, MEK, MIBK, and alcohols including
ethanol. Class meters should be used if the application
involves the use of chlorinated solvents. Meters may be
operated at rated capacity except for continuous duty service.
batch process water meter service. Not intended for use with
deionized water or demineralized water. May be used for
solvents and other liquids compatible with brass. Meters may
be operated at rated capacity. Not intended for continuous
duty service. All brass construction with 300 series
stainless steel trim.
metering alkaline pH latex products and adhesives, and some clear
liquid fertilizers (10-34-0). Operation at lower than rated
capacity is recommended. Shear sensitive liquids must be
operated at 1/3 of rated capacity or less. All ferrous
metring herbicides such as Aatrex, Atrazine, Bicep, Bladex, Dual,
Lasso, Lasso ME, Treflan, Sutan, Sutazine, and Eradicine (required
teflon seals). Operation at up to 80% of maximum rated
capacity is recommended. Available in M-5 meter only.
Use class 15 in all other meter sizes.
metering sodium hydroxide (caustic) solutions, high sulfur crude
oil (LACT and NOD) and other alkaline pH liquids including
nonabrasive asphalt emulsions and liquid feed (molasses)
supplement and some resins. Construction suitable for heated
and/or viscous liquid. Rate of flow based on viscosity to
pressure loss relationship. All ferous construciton.
metering mildly abrasive liquids, all ferrous construction.
