1. Recommended flow meter models for measuring high flow air in low-pressure environments
For measuring high flow air in low-pressure environments, E+H Promass F, Aisite Instrument ATMF series, and Comatsu TGF680 flow meters can be prioritized. The adaptation details of each model are as follows
1. E+H Promass F is a high-precision Coriolis flow meter, which is not affected by gas fluctuations and harsh environments. It is equipped with an integrated transmitter, which is flexible to operate and easy to integrate with the system.
. Equipped with Heartbeat Technology, it ensures measurement reliability and extends calibration cycles. It is highly recommended for gas measurement in large pipelines or rectangular ventilation ducts, especially suitable for compressed air scenarios. Accurate measurement can be completed in low pressure and low flow rate environments, with easy installation and negligible pressure loss. It supports maintenance free and multivariate measurement of travel volume. Insertion type adaptation for pipes with nominal diameters of DN80-1500 (3-60 "), sensor installation and removal do not require interruption of the wide finger wheel production process.2. Aisite Instrument ATMF Series This series includes two types: ATMF-AD pipe section type and ATMF-AC insertion type, with an accuracy of ± 0.5% -1.0% FS, a range ratio of>100:1, a flow rate coverage range of 0.1-120Nm/s, a pressure resistance of 0.8-4.0MPa, a temperature resistance range of -40 ℃ -220 ℃, and a caliber adaptation range of DN10-DN2000 (insertion adaptation for DN32 and above).
. No additional temperature and pressure compensation required, excellent anti vibration performance and no moving parts, response t_600x400.jpg)
3. The Kemeijie TGF680 is a plug-in pressure installed flowmeter with a measurement accuracy of ± (1.5% RD+0.5% FS), a range ratio of up to 100:1, and a measurement lower limit of 0.3Nm/s.
. Equipped with multi parameter measurement and self diagnostic functions, it can achieve continuous flow installation, adapt to large-diameter main pipes and renovation projects, and support installation and maintenance operations under pressure without stopping production.2. Which model of flowmeter to use for measuring oil
The flowmeter for measuring oil needs to be selected according to the flow range, accuracy requirements, and usage environment. The following are recommended models for different scenarios: 1 General industrial refueling scenario • 37718 electronic flowmeter: suitable for refueling oil products such as engine oil, gear oil, antifreeze, etc., flow range 20-80L/min, accuracy ± 0.3%, supports cumulative flow memory, suitable for factories, mines, auto repair shops, oil fields and other scenarios, with an inlet and outlet diameter of 1 "BSP and the ability to switch between 4 measurement units
2. Accurate fuel metering scenario • CONTOIL ® Series fuel flow meter: 1 VZO series: covering small-diameter pipeline fuel based vertical metering, with hydraulic and RE/OEM models with electronic readings, some models support pulse signal output 2 VZD2/VZP series: with electronic display or pulse output, higher protection level, suitable for scenarios that require remote transmission of measurement data DFM series: high flow differenti
