What should be used to measure the temperature of DN32 water pipes? And what type of transmitter is suitable for measuring pressure? If anyone knows the models, please share them. Thank you very much!
The pipe needs to be enlarged – it’s too narrow. A bimetallic thermometer is used on-site; for remote monitoring, it depends on your requirements: thermocouples/thermoresistors. As for the installation method, it can be threaded or flanged. Transmitters come in different models from various manufacturers; depending on your pressure requirements and the type of medium, you can find a manufacturer that can meet your needs. Since it’s a water pipe, there isn’t any major issue here.
For temperature measurement, use a bimetallic thermometer; for pressure measurement, it depends on your accuracy requirements – a standard, high-quality model will suffice
Okay, thank you. Is the pressure transmitter also installed on the expansion tube? Should it still be installed on a DN32 pipe?
An expansion tube is installed at the measurement point; of course, the thermoresistor must be selected based on the diameter of the expansion tube. The pressure can be adjusted using the standard installation method.
For temperature measurement, it seems that for pipe diameters below 40, it’s necessary to install an expansion fitting to bring the diameter up to 100. A bimetallic element is sufficient for on-site indication. Water pressure transmitters are easy to find; any transmitter designed for pressure measurement should work. Just specify your process requirements, and the manufacturer will help you choose the right one
The regulations state that for temperature measurement, if the pipe diameter is less than 80, an expansion tube must be used.
The pipe expansion is done to accommodate temperature changes; otherwise, inserting something into the pipe will reduce the flow rate. For the pressure transmitter, use a pipe with a diameter of φ16, weld it in place, add a stop valve, then attach the transmitter’s connector – that’s all. If you’re using it for water measurement, it’s best to consider the issue of heat tracing, as the pipe can freeze in winter
Pressure can be easily addressed by drilling threaded holes directly on the pipe for measurement, or by welding a ball valve after making the holes and then installing a pressure transmitter； For temperature measurement, it is necessary to use an expansion joint; if expanding the joint isn’t desired, an external temperature transmitter can be used by attaching it to the pipe, though the accuracy of measurement will be slightly lower.
What a bunch of nonsense about expansion. Gua Pi is just expanding its pipes. At the bend in the pipe, install a tee; insert the temperature probe through the tee, and that’s it, right?! .
Insert it at the right depth – it won’t affect the flow rate at all!
