1.Overview:         
       Shanghai Meixu MX-LL-116-10 thermal gas mass flowmeter is an instrument that uses the principle of heat conduction to measure the flow rate. The instrument adopts the constant temperature difference method to accurately measure the gas mass flow rate.It has the advantages of small volume, high degree of digitization, convenient installation and accurate measurement. 
The sensor part consists of two temperature sensors with reference platinum resistance.Using a bridge loop, one sensor measures the flow temperature and the other maintains a constant temperature difference higher than the fluid temperature. The flow is measured according to the relationship between the heat dissipated by the heating element and the flow velocity.The general method is to heat the very thin metal wire placed in the fluid with an electric current. Since the flow of the fluid will force the hot wire to cool, and the degree of cooling varies with the flow rate, the flow rate and flow rate can be calculated by measuring the change of the resistance value of the hot wire.Flow measurements can be made under high temperature and pressure conditions.

2.Applications:

1. Petrochemical industry, iron and steel metallurgy
2. Water supply and drainage, water conservancy irrigation
3. Water treatment, sewage treatment station (environmental protection sewage control)
4. Slurry, pulp, pulp fluid, etc
5. Distillation sold out of engineering system, condensation water measurement
6. Paper (pulp), mud, medicine, food and other industrial and agricultural production company process flow measurement and control

3.Feathers:

1. No moving parts, reduced sealing surface, greatly reducing leakage rate, convenient for installation and daily maintenance;
2. Wide measuring range, the maximum measuring range up to 20:1(liquid) or 30:1(gas);
3, accurate measurement, high precision, flange type can be up to 0.2%(liquid) or 0.5%(gas);
4. Extremely high sensitivity, can measure ultra-small flow rate, its low flow rate can be measured as 0.08m/s, electromagnetic flowmeter 0.5m/s;
5. Good repeatability, generally 0.05 ~ 0.08%, with optional small signal excision, nonlinear correction and optional filtering time;
6, small pressure loss, small diameter for the standard orifice only 1/2△P;The pressure loss above DN100 caliber began to be greatly reduced.
7. Easy calibration. In addition to standard device verification, dry calibration method can also be adopted, that is, the method of weighting weight is adopted to complete the calibration by single key operation.
8. The flow range can be changed by replacing the choke piece according to actual needs. The on-line detachable insert structure can be maintained or replaced without stopping production or interrupting flow;
9. Field display of low-power battery can read the value directly online. The display screen can read the bar chart of instantaneous flow accumulation and percentage at the same time, and display the compensation temperature and pressure indicator by switching;
10, anti - interference, anti - impurities ability is particularly strong, a variety of output forms, can be remote transmission of a variety of parameters, do not need to mix heat.
11. No temperature and pressure compensation is required for gas measurement, which can directly display the volume flow in standard conditions.
