At Meeker, we make asphalt meters to fit your budget. Whether you are a high volume asphalt plant or a smaller producer, we have the asphalt meter to fit your plant.
MASS FLOW METER (ELECTRIC OR HOT OIL)
What is a mass flow meter? To many, it is a mystery in a black box. The theory of a mass flow meter is the measurement of a mass as it travels through a tube at a fixed point in time. Keep in mind it is not measuring volume (as in a gallon of milk). It is measuring mass. Many fluids (like liquid AC) change volume as temperature changes, pressure changes, or even its composition (one delivery load to a different delivery load).
The volumetric flow rate = the mass flow rate/density of the fluid.
When liquid AC flows through a mass flow meter, the tube in which it flows vibrates. These vibrations are translated into signals. The signals are then converted to a flow rate and the output can be given in almost any engineering unit. In many cases in the USA, the rates are in gallons per minute or US lbs per minute.
The beauty of a mass flow meter is that the meter itself automatically compensates for temperature and density of the liquid AC. Meeker builds our meters so that it gives multiple outputs. We provide mass flow (lbs per minute) and we also provide temperature (F or C). By providing multiple outputs, a control can use this data for multiple uses.
Our pumps are positive placement gear pumps with jacketed relief valves.
We supply a 3 way jacketed valve with spring return so that in the event of power failure, the valve will automatically and mechanically spring to the return position.
We provide a insulation jacket for the mass flow meter with Velcro straps to allow for easy inspection and maintenance of the meter
We supply premium efficient totally enclosed fan cooled VFD motors. The pumps are driven by belts and we provide an easy to remove/replace belt guard.
PUMP TO PUMP METERING SKID (ELECTRIC OR HOT OIL)
Our pump to pump asphalt meter is an economical meter to allow you accurate control of your liquid AC without breaking the budget. The meter features a variable frequency drive gear pump and a second gear pump without a drive (free wheel). The first pump pushes liquid AC into the second pump. The second pump acts as a meter and turns. The second pump utilizes an encoder (tachometer) mounted to its shaft and it records the number of times the pump turns. A gear pump has a predetermined amount of liquid it can have inside the pump cavity at one time. Every time the pump turns one revolution, the encoder records it and the computer control can understand its volume or gallons per minute.
