2-3-1 Flow Rate Measurement Piping (JTD Model)
Warning
When doing the piping work, ensure that the connections between the connecting pipe
parts and the transmitter and three-way manifold valve are able to maintain a reliable
seal. If sealing is inadequate, there is a danger that the measured fluid will leak out and
cause scalding and other harmful health effects. If the measured fluid is harmful to the
human body, take safety measures such as wearing goggles or a mask so that it does not
adhere to the skin or the eyes, become inhaled, etc.
(1) Piping
(i) Introduction
The piping method differs depending on the device installation location and the method of
attaching to the pipeline. A method in which a three-way manifold valve (and an extension pipe,
if necessary) is connected will now be described as a general piping method.
For the JTD model, there are high pressure side and low pressure side pipe connections,
so be careful not to reverse them.
The three-way manifold valve and extension pipes are sold separately.
