Used to calibrate the liquid asphalt metering system of a drum mix asphalt plant. Available in vertical, horizontal and portable configurations. Capacity is 1,028 gallons. The tanks are mounted on load cells and have a LED readout. Jacketed asphalt lines on the tank are heated by hot oil provided by the thermal fluid heater used to heat other plant components. The tanks are not insulated since they are not normally used to store asphalt cement.
