Detailed Product Description

The Slot Dipping Device has been designed to provide convenient andsafe methods for dipping, sampling and product temperature gatheringfunctions in bulk storage tanks containing volatile and hazardousproducts.


TheSlot Dipping Device has been designed to provide a convenient and safemeans of manually measuring the levels and temperature and takingsamples of petroleum, petrochemical, chemical and other volatile orhazardous liquids 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 tanks and can be used in place of conventional gauge hatcheswith the following 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.

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


Alltank environmental protection equipments can be supported by ourservice department who can provide expert and specialist installationand commissioning service and complete 'on site' equipment maintenance,repair and servicing facilities including equipment condition surveyingand certification and maintenance training.


Theassembly consists of an upper and lower body section with a counterbalanced lever operated closing pallet in the lower section. The uppersection is sized to accommodate the dip weight or sampling device whenthe isolating pallet in the lower section is closed. The hinged capclosing the upper section is constructed to accept the bayonet fittingof the rope or tape adaptor. When the fitting is not in use it isclosed by a sealing plug. The main components - body sections, cap andclosure 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 a verysmall amount of vapor can escape and is permanently attached to thetape. When the upper section of the device is isolated from the tank bythe closure pallet the plug can be removed and the tape weight insertedwith the tape adaptor replacing the plug. Gauging can proceed whenclosure pallet has been lowered. Indicating paste is normally used whengauging spirit tanks. When gauging black oil tanks it is advisable touse the adaptor which incorporates a tape wiper. A hard Berylliumcopper strip in the adaptor holds the graduated side of the tape clearof the edge of the slot. The aperture in the upper section cap is 46 mmdiameter and will allow passage of all known standard tape weights andthe plunger of the Portable Temperature Sensor.


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


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


Thecase is opened by raising the outer body (8) with respect to the lowerend cover (11). After preliminary flushing at the required depth, thedevice is closed and the sample trapped by jerking the rope or tapewhich supports the device. Temperature variation during the time takento raise the sample and read the thermometer is negligible, because thebody (8) and disc (10) insulate the sample from its surroundings. Whenthe temperature has been read, the sample may either be returned to thetank or decanted into a sampling bottle using the special funnel (20).A flushing time of not more than 30 seconds is required for mostunheated petroleum products. Heated viscous oils may require a slightlylonger immersion of up to 1 minute.


  • Conforms to the requirements of Institute of Petroleum Measurement Manual Part IV Section 3.7.
  • Willaccommodate thermometers manufactured to the Institute of PetroleumSpecification with 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).
