Q

MEASUREMENT TECHNIQUES, TOOLS
AND INSTRUMENT:
-using ordinary glass bulb thermometer for low-temperature measurement, bimetallic and capillary thermometer for slightly high-temperature measurement or with thermocouple
wire sensor thermometer for high temperature. Thermocouple
wires with shield are usually used for a very high temperature of
as much as nearly a thousand °C. Infrared thermometer can
measure surfaces, if needed

Q

MEASUREMENT TECHNIQUES, TOOLS
AND INSTRUMENT:
-This is measured using manometer for most low
pressure measuring test. High-pressure measurement is done
with pressure gauges as well as for measuring vacuum pressure.
For high pressure, units in psi or kg/m2 or in Pascal. Vacuum
gauge uses in. or mm mercury

Q

MEASUREMENT TECHNIQUES, TOOLS
AND INSTRUMENT:
-This is determined once the distance and
the time required to traverse the field are measured. Dividing the
distance with the travel time will give speed of the machine.

A

Speed of Machine

20
Q

MEASUREMENT TECHNIQUES, TOOLS
AND INSTRUMENT:
-This can be measured using flow meter to
directly determine the velocity of flow or simply means of float
method for a certain floating device to traverse a certain distance.

A

Stream Velocity

21
Q

MEASUREMENT TECHNIQUES, TOOLS
AND INSTRUMENT:
-Cup-type Wind Anemometer or a propeller-type wind
anemometer is used.

A

Wind Velocity

22
Q

MEASUREMENT TECHNIQUES, TOOLS
AND INSTRUMENT:
-Usually determined in duct or gas piping to
determine the volume of gas passing through the duct pipe.
Thermo-anemometer are often used in measuring gas velocity.
It gives the velocity of the gas passing through a known area in
m/s

A

Gas Velocity

23
Q

MEASUREMENT TECHNIQUES, TOOLS
AND INSTRUMENT:
-For slow rotating shaft, this is done with the use
of a counter that determines the number a shaft rotates at a
given time period. For high-speed shaft, measurement is done
with the use of a tachometer, either a contact-type or a non-contact-type meter.

A

RPM of Shaft

24
