4. horizontally or vertically If the sensor was installed vertically liquid shall flow upward Pipe shall be filled fully with liquid and without bulb The direction of liquid flow shall follow the arrow marked on the sensors There shall be at least 20D straight pipe prior to the sensor and 5D straight pipe behind the sensors The wall inside should be smooth and clean There shall be no dents fouling and furrow on wall inside The axis of sensor should be aligned with the axis of adjacent pipeline Sealing gaskets shall not rise over wall inside Sensor should stay away from outside world electric and magnetic fields If necessary please People are our prime mover RLT Instrumentation Unit of RLT Group take effective screening measures in order to avoid external interference If sensors were installed outdoor please take water proof measure to protect the amplifier By pass pie was suggested to install so that liquid transference does not have to be stopped during overhaul lf the fluid contains impurities filter shall be installed Filter mesh is up to the size of impurity Generally mesh number 20 60 was suggested When there s bulb in the fluid air eliminator should be installed The entire pipeline system should be sealed will Users should fully aware of the corrosions of medium to protect sensor against corrosion 2 Operation and adjustment To keep liquid clean and no fiber and impurity Please open valve sl
5. owly and fill the sensor gradually High water hamper to the empty sensor was prohibited Normally sensor maintenance period is six months During cleaning of sensor please pay attention not to damage measurement cavity parts especially the turbine Before assembly please pay attention to the relationship between the turbine and flow guider For storage please clean the liquid inside the sensor and cover 2 ends of the sensor against impurity entering the sensor Please keep the sensor in dry and clean place For equipped filter please clean it periodically When it s not used please clean and store it just as to sensor Sensor s transmission cable can be laid overhead or underground please put the cable into metal pipe if it s buried underground Before sensors installed please connect electrically the sensor to indicator to see whether indicator shows flow when user rotates the turbine If no flow displays on indicator please check the relevant part to kill trouble before installation 6 People are our prime mover 4 Maintenance and common fault Sensors may have a general should not exceed six months No Display Instrument shows on flow Display Instrument works well but shows no flow Display instrument does work steadily or measurement is not correct fault Please shoot the Table 3 1 No powered or wrong voltage 2 Fault with display instrument 1 Sensor and display instrument w
