MassSense* Liquid Density Meter
The MassSense* Liquid Density Meter or LDM
revolutionizes the measurement of liquid density with
its small integral packaging and sensitive measuring
capabilities. The heart of the LDM is a patented* silicon
sensing tube that vibrates at a very high frequency above
20 kHz, which eliminates the impact of environmental
vibrations on density measurement. Silicon sensing tube
technology is lighter and stronger than traditional metal
sensing technology. The result is an instrument that can
detect even the slightest changes in density with the
industry leading performance specifications. Installation
in a process is normally on a controlled flow bypass. An
internal orifice in the LDM directs a small portion of the
bypass flow through the vibrating detector. Approved for
Hazardous Locations & IP67 Sealed.The LDM has ATEX, UL,
and CUL approvals for hazardous environments.
Features
■ In-Line, Real Time
The small internal volume of the silicon sensor and
high-speed digital processing results in very fast
density detection. This is important in those applications
where speed is important.
■ Low Power Consumption
The LDM's, 400 mW, power consumption makes the
instrument ideal for portable and remote applications.
The instrument can be powered using a small solar
panel, external battery, for remote or power adapter.
■ Advanced Measurement Capabilities
The LDM can be programmed to calculate specific
gravity, brix, plato, concentration, as well as other
custom measurements.
■ Unmatched Resolution and Sensitivity
The LDM resolves density to 0.000001 g/cc
and has an accuracy of 0.0001 g/cc.
Applications
Concentration Measurement: Chemical Concentration
Density measurement provides the composition and
quality of fluids. The density measurement can detect
with binary chemical concentration of the materials.
Specific Gravity The liquid density meter can provide
specific gravity which is a common measurement in
the production of beer, wine, and other beverages. No
sample preparation is required for the LDM.
Fuel Quality Monitoring Density can be used to identify
and monitor the composition and quality of fuels.
Density is also the preferred method to determine the
composition of E85 and biofuel. Other uses have been to
confirm the correct weight of fuel for airplanes.
Salt Water Solutions The silicon sensor design and
construction allows the meter to be used in salt water
and other corrosive situations. Self-cleaning systems
are available in the case that the process requires a
mechanism for cleaning between samples.
