Detailed Product Description

The Slot Dipping Device has been designed to provide convenient andsafemethods for dipping, sampling and product temperaturegatheringfunctions in bulk storage tanks containing volatile andhazardousproducts.


TheSlotDipping Device has been designed to provide a convenient and safemeansof manually measuring the levels and temperature and takingsamples ofpetroleum, petrochemical, chemical and other volatile orhazardousliquids in bulk storage tanks, in pressures of up to 40"(1016 mm) WG.It is available in 6" (150 mm) size and is mounted on theroofs of tanksand can be used in place of conventional gauge hatcheswith thefollowing advantages :

  • Negligible loss of vapor.
  • Operators not exposed to hazardous vapors.
  • No product spillage due to wiping of the tape.

The device can accommodate both heavy and light dip weights and also the Temperature and Sampling Device.

TheTemperatureand Sampling Device has been designed to provide a means oftakingsamples and temperature of products stored in bulk in thepetroleum,petrochemical, chemical and allied industries. When used inconjunctionwith the Slot Dipping Device which is suitable forpressures up to 40"(1016 mm) WG, loss of vapor is greatly reduced.


Alltankenvironmental protection equipments can be supported by ourservicedepartment who can provide expert and specialist installationandcommissioning service and complete 'on site' equipmentmaintenance,repair and servicing facilities including equipmentcondition surveyingand certification and maintenance training.


Theassembly consists of an upper and lower body section with acounterbalanced lever operated closing pallet in the lower section. Theuppersection is sized to accommodate the dip weight or sampling devicewhenthe isolating pallet in the lower section is closed. The hingedcapclosing the upper section is constructed to accept the bayonetfittingof the rope or tape adaptor. When the fitting is not in use itisclosed by a sealing plug. The main components - body sections, capandclosure pallet are constructed in Aluminum alloy.


The lower body section is drilled to ASA 150.

Hand Gauging

TapeAdaptor has a small clearance around the tape through which only averysmall amount of vapor can escape and is permanently attached tothetape. When the upper section of the device is isolated from the tankbythe closure pallet the plug can be removed and the tape weightinsertedwith the tape adaptor replacing the plug. Gauging can proceedwhenclosure pallet has been lowered. Indicating paste is normally usedwhengauging spirit tanks. When gauging black oil tanks it is advisabletouse the adaptor which incorporates a tape wiper. A hardBerylliumcopper strip in the adaptor holds the graduated side of thetape clearof the edge of the slot. The aperture in the upper sectioncap is 46 mmdiameter and will allow passage of all known standard tapeweights andthe plunger of the Portable Temperature Sensor.


Eithera gauging tape or a PVC covered wire rope can be used withthecorresponding adaptor. The method of sampling follows closely thatforgauging except that the cap on the upper chamber is opened andthesampling device is placed in the upper section and thetape/ropeconnected. The tape adaptor or rope adaptor is inserted in thecap andafter lowering the pallet, sampling can proceed.


Theunit consists of a sample container which can be opened andclosedbeneath the liquid surface by the thermometer containment tubewhich isattached to a rope or graduated tape. The materials arepredominantlyStainless Steel and Brass.


Thecaseis opened by raising the outer body (8) with respect to the lowerendcover (11). After preliminary flushing at the required depth, thedeviceis closed and the sample trapped by jerking the rope or tapewhichsupports the device. Temperature variation during the time takentoraise the sample and read the thermometer is negligible, becausethebody (8) and disc (10) insulate the sample from its surroundings.Whenthe temperature has been read, the sample may either be returned tothetank or decanted into a sampling bottle using the special funnel(20).A flushing time of not more than 30 seconds is required formostunheated petroleum products. Heated viscous oils may require aslightlylonger immersion of up to 1 minute.


  • Conforms to the requirements of Institute of Petroleum Measurement Manual Part IV Section 3.7.
  • Willaccommodatethermometers manufactured to the Institute of PetroleumSpecificationwith overall and immersed lengths of 340 mm and 65 mmrespectively.
  • Samples and Temperatures can be taken at various depths of product including from a layer within 4" (100 mm) of tank bottom.
  • Sample volume is 0.4 liters (0.7 pts, 25 in3).
