Do not install the transmitter in a corrosive atmosphere.

If this cannot be avoided, maunal must be CAUTION adequate ventilation as well as measures to prevent the leaking of rain water and the presence of standing water in the conduits. This instrument has been tested and certified as being intrinsically safe or explosionproof.

A failure to abide by these restrictions could Type 4X Note 2. II Pressure Transmitters Category: Maximum Process Temperature Tp.

Since this will cause errors in the measurement output, manjal the proper piping method covered with a plastic cap to keep out dust. This cap must for the process fluid gas, liquid, or steam. Pay careful be removed before connecting the line. Be careful not attention to the following points when routing the impulse to damage the threads when removing this cap.

Never piping and connecting the impulse piping to a transmitter. To maintain proper sealing, wind sealing If condensate, gas, sediment or other extraneous tape around the nipple threads. To pipe by fastening a U-bolt to its mounting bracket. Before connecting the and low impulse lines, the density difference of the fluids transmitter to the process, study the transmitter in the two lines will cause an error in the measurement installation location, the process piping layout, and pressure.

When measuring flow, impulse lines must be the characteristics of the process fluid corrosiveness, routed together so that there is no temperature difference toxicity, flammability, etc. This cap must be removed before connecting the piping. Be careful not to damage Tap valve Drain plug the threads when removing this cap. Never insert a Drain valve screwdriver or other tool between the cap and port threads to remove the cap. Select the type of valve most appropriate for the application.
