7. indicator first In such a case the indicator should be protected from mechanical damage during fixing the capillary The capillary should be carefully unrolled Do no pull the coil apart and attempt to correct the spring like effect by pulling The following guidelines should be followed Protect the sensor diaphragm against the ingress of foreign matter or sharp objects Secure the capillary at the start and completion of every bend Bends should not have a radius of less than 25mm For underground runs enclose the capillary in a duct Although the capillary covering can be buried This is not recommended unless precautions are taken to prevent damage from later excavation work Ensure the capillary is not exposed to higher than ambient temperature ON NO ACCOUNT ENCASE THE CAPILLARY IN CONCRETE Sensor To ensure accurate measurement the tank mounted sensor must be installed at the level detailed in the purchase order questionnaire E Side of tank screwed connection Sensor connected via 34 BSP female connection surplus capillary should be neatly coiled close to the tank IF The sensor assembly is inserted through and bolted to tank top a gasket should be used between tank and sensor flange sufficient capillary should be coiled at the tank to enable the complete IF sensor assembly to be withdrawn from the tank for service or cleaning IM The sensor with the stainless steel capillary is passed through the tank cut out T
8. l face Cleaning EF EFM and IM types of sensors is seldom necessary as these sensors have a larger diameter pressure sensitive area in contact with the process In the rare event of this being needed First drain the tank remove the sensor and gently wash the pressure sensitive diaphragm with a non corrosive solvent compatible with the liquid being measured SECTION 4 MALFUNCTION AND REMEDY Symptoms a The gauge indicates a value more than which is known to be in the tank b The gauge indicates a value less than which is known to be in the tank c The pointer gradually returns to zero d The pointer shows no movement with a variation in the liquid level e The pointer starts to make a second sweep of the scale f The Indication is erratic and unstable varies with temperature Remedy A 1 Check that the tank dimensions including any slope relative to sensor and specific gravity with information given to Measurement Resources at the time of order Providing the actual dimensions are within 10 of data supplied with the order a new dial can be supplied to correct discrepancies A variation over 10 will require the instrument to be returned to the factory for recalibration 2 Check that the tank sensor is not choked with congealed liquid or sludge Clean as needed 3 Check that the tanks ventilation system is not blocked If the gauge shows a normal reading when the manhole cover is opened the vent pipe should be checked cleared 4
9. ndard All indicators are stainless steel and weatherproof UNDER NO CIRCUMSTANCES SHOULD ANY ATTEMPT BE MADE TO DISCONNECT ANY PART OF THE SEALED SENSOR CAPILLARY INDICATOR SYSTEM DESCRIPTION OF OPERATION The sensor is installed so the head pressure of process liquid acts against a stainless steel diaphragm contained in the stainless steel sensor this is connected by capillary tubing to a rated diaphragm within the remote indicator The total internal volume of the diaphragm capillary tubing and senor is charged with an inert temperature stable gas and sealed When the sensor is fitted to the tank or vessel the liquid head hydrostatic pressure acts on the diaphragm and causes pressure to be transmitted via the capillary tubing to the indicator With an increase in pressure the indicator diaphragm distends and causes a precision mechanism to move the pointer over the scale This is graduated in mass head or volume units to suit the application Providing constant self powered remote indication of the tanks liquid level SECTION 2 INSTALLATION Capillary and Indicator To gain long life and trouble free operation care should be taken during installation to avoid damage to the capillary Whenever possible installation should commence by fixing the indicator in position reducing the risk of the instrument being damaged when the capillary is unrolled With the internal sensors IF and IM it may not be practical to commence by mounting the
