Description of Remote 4~20mA/Pulse turbine flow meter
GXTFM-R remote 4~20mA/pulse turbine flow meter is the use of
advanced low-power single-chip microprocessor technology developed
turbine flow sensor and display totalizer integration of new smart
meter, with a compact structure, intuitive readings clear, high
reliability, without outside power interference, anti-lightning,
obvious low cost advantage, it is widely used to measure the closed
pipe and stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3,
carbide not corrode, and no fibers, particles and other impurities,
kinematic viscosity at operating temperature is less than 5 ×
10-6m² / s of liquid, for kinematic viscosity more than 5 × 10-6m²
/ s of liquid, can be quantitative control, excessive alarm, etc.,
is an ideal flow metering and energy meter.
Measurement objects: oil, organic liquids, inorganic liquid,
liquefied petroleum gas, natural gas, coal gas and cryogenic
fluids.
Features
- High accuracy, generally up to ±1%R, ±0.5%R, high accuracy up to 0.2%R
- Good repeatability, short-term repeatability up to 0.05%~0.2%, in
the trade settlement is the preferred choice of flow meter.
- Output pulse frequency signal, no zero drift and strong
anti-interference ability.
- High frequency signal(3~4KHz) can be obtained, the signal
resolution is strong.
- Wide range, medium and large diameter up to 1:20, small caliber
1:10.
- Can be customized, for example Low temperature type, Bi-Directional
type, Mixed sand type and Underground type etc.
- Can be made into an insert type, suitable for large diameter
measurement, the pressure loss is small, the price is low, take it
out with not cut off the liquid.
Applications
- Liquefied petroleum gas, refined oil and light crude oil transport
and gathering stations, the first and terminal station of large
crude oil pipeline for trade settlement.
- Widely used in petroleum, chemical, metallurgy, paper and other
industries to measure the volume of liquid flow and total volume.
Specifications
Specifications of Remote 4~20mA/Pulse turbine flow meter
GXTFM-R Remote 4~20mA/Pulse turbine flow meter does not have a
display function, only the flow of remote signal output, signal
flow can be divided into pulse signal and current signal,
Especially suitable for the secondary display instruments, PLC, DCS
and other control systems with the computer.
