APR transmitters with a remote diaphragm seal 7 4 2 Transmitters should not be installed in places where the diaphragm made of 316L steel 00H17N14M2 would be subject to corrosion by the medium being measured If possible transmitters with diaphragms made of Hastelloy C276 should be used or other means of protection applied e g in the form of a separating liquid or transmitters with diaphragm seals adapted for measuring aggressive mediums according to catalogue cards DIAPHRAGM SEALS should be used 8 INSTALLATION AND MECHANICAL CONNECTIONS The APC APR transmitters can operate in any position When installed on an object with a high temperature medium it is advantageous to mount the transmitter in a horizontal position with the packing gland pointing downwards or to the side in such a way that the transmitter is kept away from the stream of rising hot air When the measurement range is small the reading can be affected by the position of the transmitter and by the configuration of the impulse lines and the way in which they are filled with liquid This error can be corrected using the zero setting function 8 1 APC Installation and connections 8 1 1 The APC transmitters can be mounted directly on rigid impulse lines Where connectors are used as in figures 5a 6a and 7a it is recommended that connection sockets be used as shown in figure 5b 6b 7b or 7c It is recommended that sockets labeled

Finally if necessary reverse the display mode using the RAPORT 01 program version 3 14 or higher The procedure for rotating the display mode involves an automatic reset of the transmitter current 1 change It is therefore recommended that this operation be carried out outside the process circuit or that the regulation method be previously set to manual control 10 2 8 Illumination of the display can be switched on or off This is done using switch 1 after unscrewing the cover with the window panel only outside the explosion hazard zone The ON position means that illumination is turned off As the display illumination components are connected in series in the current circuit an additional drop of approximately 3V DC can be expected at the transmitter s signal terminals 17 DTR APC APR AL 01 ENG 10 2 9 Configuration of the APR 2200 AL and APR 2200EEx AL transmitters to measure the level density of liquid and phase boundary To simplify the mathematical operations we introduce the density coefficient of the medium Xp Xp Pmedum g em Prater at rc g m Since the density of water at 4 C is 1 gicm the density coefficient Xp is numerically equal to the density of the me dium expressed in glem To determine the hydrostatic pressure of a column of liquid in mm H20 it is sufficient to multiply the height of the column h mm by the density coefficient of the liquid Xp Since it is easy to determine the h
