Definition and terminology
Terminology Definition
A
Analogue output
A type of variable output that has a value proportional to the measured
quantity. When the analogue output is in the range of 1 to 5 V, it will vary
continuously, following the change of flow.
F
F.S. (Full span, Full scale)
Stands for "full span" or "full scale", and indicates varied analogue output
range at rated value. For example, when analogue output is 1 to 5 V, F.S. =
5[V] - 1[V] = 4[V], (ref. 1%F.S. = 4[V]x1% = 0.04[V])
The maximum measuring range or change in analogue output over the
maximum measurement range.
N Non-linear output Indicates non linear output.
O
Operating fluid temperature
The fluid temperature range within which the product will meet all published
specifications.
Operating humidity range
The ambient humidity range within which the product will meet all published
specifications.
Operating pressure range
The pressure range within which the product will meet all published
specifications.
Operating temperature range
The ambient temperature range within which the product will meet all
published specifications.
P Part in contact with fluid A part that comes into physical contact with the fluid.
Pressure characteristic
The amount of variation in the analogue output when the supply pressure is
changed.
Proof pressure The pressure beyond which the product will be damaged.
R
Rated flow range
The flow range within which the product will meet all published
specifications.
Rated pressure range
The pressure range within which the product will meet all published
specifications.
Repeatability
Reproducibility of the analogue output value, when the flow is repeatedly
changing.
Response time
The time from when the flow is applied as a step input (when the flow rate
changes from 0% to 100% instantaneously) until the analogue output
(voltage) reaches 90% of the actual flow rate.
Ripple Indicates pulsation.
T
Temperature characteristic
The amount of variation in the analogue output or display value when the
ambient temperature is changed.
