Gas turbine flowmeter with oil cup

Gas turbine flowmeter with oil cupAdditional charges are required, please consult customer service for details.

Gas turbine flowmeter with oil cupThere are multiple calibers and configurations, not *. The above quotation is for reference only and needs to be selected and quoted based on actual working conditions.

Below is a detailed introduction to gas turbine flow meters.

When measuring gas turbine flow meters online, the density of the medium changes with temperature and pressure. To achieve accurate measurement, it is necessary to simultaneously track and detect the temperature and pressure of the medium, and convert the volume flow rate under different operating conditions into the volume flow rate under standard or agreed conditions.

1) High precision, good repeatability, low pressure loss, and good seismic performance;

3) Integrating microprocessors, flow sensors, high-precision temperature and pressure sensors, directly measuring the flow rate, temperature, and pressure of the measured gas, and automatically performing flow tracking compensation and compression factor correction calculations;

5) Low power consumption, can be powered by internal batteries or external power sources;

7) Can be used in conjunction with IC card prepaid system for easy trade settlement;

Unless otherwise specified, the product is manufactured with a precision level of 1.5. For other accuracies, special instructions are required for customization when ordering.

⇒Gas turbine flowmeter with oil cupModel specifications and basic parameters (see Table 1)）

♦Standard condition: P=101.325kPa T=293.15k

a. Environmental temperature: -25~+80 ℃ b. Medium temperature: -20~+60 ℃

♦Electrical performance indicators

a. Internal instrument power supply: 1 3.6VDC lithium battery, which can work normally when the battery voltage is between 3.1-3.6V;

c. External power supply:+24VDC ± 15%, ripple ≤ ± 5%, suitable for 4-20mA output, pulse output, RS-485, etc;

2. Power consumption of the whole machine: external power supply,<1W

Internal GPRS power supply: According to the daily average communication frequency (2-12 times), it can work continuously for one to five years.

1) Base pulse signal: (used for instrument calibration):

≤1V。

Set by software, the default output is the corrected working condition volume flow pulse, with an amplitude of: high level ≥ 20V, low level ≤ 1V.

a. TTL output amplitude 0-3V, output pulse width ≥ 50ms.

4 Current output:

Directly proportional to the standard volumetric flow rate, 4mA corresponds to 0 Nm3/h, and 20mA corresponds to the Z standard volumetric flow rate (this value can be set).

1. Scope of use

2) There is no fluid medium with short interval time and large flow fluctuation amplitude

Determination of specifications

Due to the integration of temperature, pressure, and flow sensors, the online temperature and pressure compensation flowmeter tracks and detects the temperature and pressure of the medium online, and performs automatic compensation and compression factor correction calculations. Therefore, it has excellent low-pressure and high-pressure measurement performance, and is particularly suitable for the precise measurement of various single-phase gases such as natural gas. According to the different requirements of users, our company provides turbine flow meters with different precision levels.

1) When the flow meter requires flow pulse signal output, an external power supply with a supply voltage of+24VDC is required.

3) When the flowmeter requires RS485 data communication, a+24VDC power supply needs to be added.

⇒Installation precautions

♦Users should install a filter in front of the gas turbine flow sensor when installing it.

♦Before using the instrument, the pipeline should be cleaned in advance.

♦When installing a flowmeter, do not weld the pipeline after installation to avoid burning out the flowmeter core. If the flowmeter burns out the inner core due to welding pipeline, it is not covered by the warranty.

♦If it is a temperature and pressure compensation type, the pressure sensor valve on the instrument should be opened first.
