Micro gas flowmeter parameters and quotes

The micro gas flowmeter USES energy to measure the flow, most of which can be divided into two ways. One way is to place an ironing part in the fluid dynamics of the flow. The temperature of the ironing components will eventually change with the water flow, and the flow can be measured according to the cooling level of the ironing components.Another way is to add the necessary calorific value to the fluid mechanics, since the energy flows with the fluid mechanics, and the flow can be calculated by monitoring the calorific change at the opposite point.The former is commonly referred to as the thermal conductivity type, and the instruments assigned to this type of measurement include anemometers and hot-ball anemometers.The latter is generally called calorific type, and the instrument panel belonging to this kind of measurement mode includes Thomas flowmeter and boundary layer flowmeter.

Micro gas flowmeter parameters and quotesfeatures

 

1, can not move the component, sudden surface reduction, greatly reduce the leakage rate, conducive to the installation and maintenance;

 

2. Wide measurement range, with a larger measurement range of up to 20:1 (liquid) or 30:1 (gas);

 

3. Accurate and accurate measurement verification, with flange type reaching 0.2%(liquid) or 0.5%(gas);

 

4. It is highly sensitive and can measure ultra-small flow rate. The measurable low water flow rate is 0.08m/s, and the electromagnetic induction flowmeter is 0.5m/s;

 

5. Good repeatability, generally 0.05 ~ 0.08%, with optional small data signal extraction, discrete system adjustment, filter time selection;

 

6, the pressure damage is small, the caliber is only 1/2 of the standard orifice plate P up and down;The pressure damage around DN100 specification has been greatly reduced at the beginning;

 

7, the calibration is convenient, in addition to the selection of standard equipment metrological verification, but also can choose the dry test calibration method, that is, the standard weight method, single key can be calibrated in practice;

 

8. The flow category can be changed according to the specific need to dismantle and replace the choke parts. Free online detachable plug structure can be maintained without shutdown, and continuous flow maintenance or dismantling;

 

9. The power consumption rechargeable battery can display the information on the spot, and can directly read the range online for free. The display can also load the instantaneous velocity flow accumulation flow and percentage bar graph, and can convert the information to show the compensation temperature and compensation pressure range;

 

10, anti-interference, anti-residue ability is super, a variety of output, can transmit a variety of main parameters, the application need not mix heat.

 

11, measuring gas without temperature and pressure compensation, can immediately show the information standard condition volume flow.

 

Three, the main parameters

 

Measurement range: 0-20 cm/s to 1-100 cm/s.(expanded in relation to water and other substances)

 

Measurement time: 2-10 seconds, according to measurement standard

 

Linear error: <5%(matching slope)

 

Repeated capacity dimensional tolerance: <2%

 

Switching power supply operating voltage: 24V dc ±10%

 

Resistor load: 0-600 ohm
