Page 12: Selecting The Installation Location
3.1 Selecting the Installation Location Prior to product installation, check the model, specifications and installation location for the transmitter. The transmitter is designed to withstand severe environmental conditions. However, follow the enlisted precautions while selecting the installation site to ensure stable and accurate operation for years. -
Page 13: Housing Rotation
Choose gasket according to the properties of the process medium and the temperature range. Pay attention to the bolt balance lock. 3.2.2.3 Clamp Connection Choose gaskets that meet specified standards to avoid excessive clamp locking and squeezing gasket. Excessive locking of clamp may damage the sensing diaphragm and cause measuring error. -
Page 14: Mounting Requirements
3.2.6 Conduit Installation Improper sealing of connections may damage the transmitter due to excess moisture accumulation. Mount the transmitter with electrical housing positioned downward so that the excess of moisture is condensed and drained out from the casing. Secondly, install wiring with a drip loop and ensure the bottom of the drip loop is mounted lower than the conduit connections or the transmitter housing to avoid moisture accumulation in the housing. -

3.4.2 Full Span Adjustment • For full span adjustment, ensure that the vessel is filled with process medium to the maximum level. • Maintain static pressure value within the minimum and maximum pressure range. • Using local push buttons set output for lower and upper limit of the full scale i.e., 4mA and 20mA, refer to section 5.2 of this manual for detailed key operations. -
Page 17: Sealed Container Level Measurement: Single Flange Level Transmitter
For accurate measurement, install the transmitter at a location where liquid level and temperature fluctuations are minimal. 3.5.7 Sealed Container Level Measurement: Single Flange Level Transmitter Use a single flange diaphragm system for sealed container level measurement. Increase the isolation tank and multiple shut-off valves. Periodically open the drain/vent valve to clear off the residual gas and liquid in the guiding pressure tube for higher accuracy. -
Page 18: Power Supply Specifications And Connection
Power Supply Specifications and Connection • Use independent linear direct current power supply for pressure transmitter. Large resistive load results in high pressure drop. • Therefore, it is recommended to consider the resistance across the signal cable, display meter and other equipment to ensure sufficient voltage is provided to the pressure transmitter for its normal operation. -
Page 19: Cable Protection System
4.3 Cable Protection System Apply following cable protection measures to protect the connecting cables from various factors that affect negatively on the cable lifetime. 4.3.1 Standard Protection System • To avoid liquid flowing along with the cable into the terminal box, configure a U-shaped ring between pull box and pressure transmitter as shown in the figure below. -
