11.1 General Specifications

Measurement method: Microwave phase difference method
Measurement range: The density measurement range is set by setting the lower (4mA) and upper
(20mA) ranges of density measurement. The measured object fluid is required to be free from cavities
and have fluidity. Please contact Toshiba for ranges other than those described below.
Lower density measurement range: 0 to 49%TS
Upper density measurement range: 1 to 50%TS
Span range:
Setting step:
Note 1: The density measurement range above may change depending on the fluid to be
measured. Therefore, we recommend you check the density of the fluid beforehand with
a sample test. In addition, contact us about the following items beforehand because the
fluid viscosity may limit the maximum flow rate. (1) Fluid to be measured (2) Density
upper limit (3) Viscosity (4) Flow rate upper limit (5) Temperature upper limit.
Note 2: TS (total solids) = Dissolved materials + Floating materials
Note 3: Span = Density meter range upper limit - Density meter range lower limit
Repeatability : ± 0.01%TS
Note 1: Resolution measured in a single unit.
Note 2: Refers to the value at the measuring point of 5% or greater of FS (full scale) in measuring
a simulated reagent.
Note3: Repeatability that can be confirmed using the simulated reagent:
Full-scale 2%TS or greater
Less than 2%TS
* Measured values are taken at measurement points of 5% FS or above in the
measurement using the simulated reagent.
* Full-scale is the maximum value of the measurement range on the upper side of the
density measurement range.
* If the density distribution in the piping system is not even, manual analysis data and the
indication value of the density meter may not be the same.
Linearity: When full-scale 2%TS or greater : ± 2%FS
When less than full-scale 2%TS : ± 4%FS
Note: Refers to the measuring point of 5% or greater of FS (full scale) in measuring a simulated
reagent.
