6.2 Piping It is generally recognized that there are appropriate positioning relationship between the transmitter and main process piping for accurate measurement to avoid harmful gas or liquid accumulation. General recognizations are; 1- Mount transmitter below main process piping for liquid or steam measurement. 2- Mount transmitter above main process piping for gas measurement.
Typical examples of piping Manifold valve 1 Flow measurement (in case of gas) Impulse pipe Place the transmitter above the differential pressure source. Stop valve Process pipe Differencial pressure source (orifice) Differencial pressure source (orifice) 2 Flow measurement (in case of liquid) Place the transmitter below the differential pressure source. Process pipe Make piping so that gas in the impulse pipe is not delivered to the transmitter, and incorporate gas reservoirs as required.
Important (1) Protection is required to prevent dust from entering through the atmospheric air inlet after installation of the manifold valve. (2) If process pressure range is narrow (below 10kPa (1000mmH2O)), the following should be considered. • Pressure variation due to wind around atmospheric air inlet • Temperature variation near process taps • Difference in atmospheric pressure between process tap and transmitter location.
Cautions on impulse piping • For liquid, the impulse pipes should have an upward slope of 1/10 or more between the process connection and the transmitter to prevent accumulation of gas, etc. in the detecting unit. • For gas, the impulse pipes should have a downward slope of 1/10 or more between the process connection and transmitter to prevent accumulation of moisture, etc. in the detecting unit.
6.2.2 Piping of pressure transmitter type : FKP Removal of protective cap The process connection port of the transmitter is fitted with a protective cap. Before piping, remove the cap carefully. When removing the cap, carefully protect the threaded portion and sealing face from damage. Connection of transmitter and impulse pipe • Impulse pipe should directly be screwed into the transmitter.
Typical examples of piping 1 Gas measurement Manual valve Impulse pipe 0 10 0 Place the transmitter above the pressure source. 20 40 60 80 Stop valve Pressure source 2 Liquid measurement Process pipe Pressure source Stop valve Impulse pipe 0 10 0 Place the transmitter below the pressure source. Make piping so that gas in the process pipe is not delivered to the transmitter, and incorporate gas reservoirs as required.
6.2.3 Piping of level transmitter type : FKP for open tank Seal on mounting flange face When mounting the flange on the pressure side, a gasket should be inserted as follows. Transmitter flange Process side flange 0 10 0 20 40 60 80 Gasket Important On the projection type, be sure to use a gasket with an internal diameter larger than the flange to prevent the gasket form touching the seal diaphragm.
Caution of installation • Restriction on H1 Liquid level is not proportional to the transmitter output at some points inside the seal diaphragm. Therefore, H1 should be set higher than the value shown in the table below. • In order to prevent vibration, the transmitter body should be installed at a vibration-free place. • Do not shock the seal diaphragm by hitting hard object against it, for example. • Take care not to apply an excessive force to the flange during connection.
7 WIRING Cautions on wiring (1) Application of a voltage exceeding 60 V DC or 40 V AC (exceeding 32 V DC or 23 V AC when arrester equipped) between “+” and “–” terminals may result in damage to the transmitter. (2) Use a shielded cable for the transmission line where possible. (3) Avoid installation of signal cable and power cable in same conduit or cable tray in order to prevent increased noise. Also, do not bring the signal cable close to large electrical equipment.
Terminal block connection diagram Tighten the terminal screws (M4 x10) to a torque of approximately 1.5 N•m (15 kgf•cm) <11ftlb> so that the wires will not loosen. After connection, fasten the cover until it does not turn. Terminal – CK – + CK + 10.5 ~ 45 V DC (Analog type) 16.
