True or False. If false, mention the word/s that makes the statement false

1. A capactive sensor is an active device uses crystal that as the sensing element to measure
pressure.
2. Paddle wheel sensor is a passive device that generates change in resistance that will be the basis
of the fluid velocity.
3. Ultrasonic sensor generates sonic waves that travel upstream and downstream, if the difference
on time travel of the two direction is zero, it means that the fluid motion speed is constant.
4. A thermocouple is an active device that uses seebeck effect to measure temperature.
5. Liquid in glass thermometer uses elastic bourdon tube that elongates when there is a presence of
high temperature.
6. One advantage of using positive displacement flow meter is that they don't have moving parts
compare to other mechanical instruments.
7. Volumetric flow rate of PDFM is calculated by the product of its cross section area and the rotor
velocity.
8. When the sensing element of an RTD device detects an increases change in temperature, the
resistance of it will decrease.
9. One disadvantage of using a capacitive sensor is that it uses high power consumption.
10. The number of electrical pulses generated by the paddle wheel is directly proportional to the
number of magnets passing by the sensor.
