Features of Heating oil

The heat transfer oil furnace uses heavy oil, light oil or combustible liquid as fuel. Heat transfer oil is the heat carrier. The circulating oil pump is used to force the liquid phase to circulate. The heat energy is transferred to the heating equipment. Then it returns to the reheated DC special industrial furnace.

Thermal oil is widely used in petrochemicals, textiles, printing and dyeing, plastics, rubber, food processing, wood processing, asphalt heating, carton production, vegetable dehydration, baking varnish, casting sand mold drying, etc. It can also be used for baking, steaming, shaping, melting and drying at ≤ 350oC.

Heating oil flow meters

What kind of flowmeter is good for measuring heat transfer oil? What are the main types?

Heating oil flow meters are based on the temperature of the heat transfer oil on the customer site to select the corresponding heat transfer oil flowmeter.

Generally, vortex flowmeters and high-temperature oval gear flowmeters can be used for temperatures around 200 degrees.

Orifice flowmeters can be used for high temperature, so as to ensure the durability, practicability, and long service life of the heat-conducting oil flowmeter. The advantages of the heat-conducting oil flowmeter are high measurement accuracy and good stability.

Suitable for all kinds of heat-conducting oil flow meters. The complete system of heat-conducting oil flow meters consists of flow sensors, intelligent liquid crystal heat totalizers, temperature and pressure compensation components and instrument valve components.

Let’s briefly compare the advantages and disadvantages of heating oil flow meters:

  1. Vortex flowmeter

The vortex flowmeter is a volume flowmeter that measures the volume flow of gas, steam or liquid, the volume flow of standard conditions or the mass flow of gas, steam or liquid based on the Karman vortex principle. When the fluid flows through the dust collector rod of the vortex flowmeter, a vortex is formed. The frequency of vortex shedding is proportional to the fluid velocity. Temperature and pressure compensation can be configured.

Advantages: relatively wide range, convenient and simple installation;

Disadvantages: poor shock resistance, high cost if the temperature of the measured medium is high.

  1. Orifice flowmeter

The nozzle of the temperature and high pressure welding orifice plate adopts the standards of the Ministry of Water Resources and Electric Power. The standard is (DG0700-DG0750). Welded integrated orifice plates for high temperature and high pressure are mainly used for measuring orifice plates for high temperature and high pressure steam flow and high pressure flowing water in power plants.

Advantages: good shock resistance, high temperature resistance, relatively reasonable price;

Disadvantages: The range is relatively narrow, only 1:3, which makes installation more troublesome;

  1. Oval gear flowmeter


The flow measurement has nothing to do with the fluid flow state, and the measurement range is wide.

The oval gear has high flow measurement accuracy and is suitable for the measurement of the flow of high-viscosity media.

There is no need for straight pipe sections before and after the flowmeter, even if the flowmeter is close to the valve, elbow, shrinking pipe, or expanding pipe, there is no need to install straight pipe sections.

Disadvantages: The product is heavy. It is not available when the temperature exceeds 200℃.
