Description
Metal Tube Variable Area Flow Meter consists of a tapered tube, typically made of steel with a ‘float’, made of SS or PTFE. LZZ series intelligent Metal Tube Variable Area Flow Meter adopts the international advanced technology without contact and no hysteresis detecting changes in the angle of magnetic field of magnetic sensor, and with high performance MCU,which can realize LCD display:the instantaneous flow, totalizer ,loop current.environment temperature,damping time,small signal cut-off .
Optional 4~20mA transmission(with HART communication),pulse output, high and low limit alarm output function,etc,The type of intelligent signal transmitter has high precision and reliability,which can fully replace the same type imported instrument, and it also has high price performance, parameter standardization online and power failure protection,etc features.
The features of far transmission output of the instrument:
The Large LCD display can display the instantaneous flow and total flow at the same time and also display the instantaneous flow simulation.
The upper display the instantaneous flow, lower display the total flow
The instantaneous flow range: 0.000-99999
Cumulative flow display range: 0.00-99999999
Current display range: 3.80-21.00 mA
Instantaneous flow percentage display: 0-100%
The pointer Angle range: 0.00 to 90.00 °
Ambient temperature range: – 20 – + 80 ℃
The cumulative small signal removal range: 0-10%
Damping time setting range: 0 to 10 seconds
A variety of optional instantaneous flow and total flow unit, after the the unit switching, the range is automatic conversion.
Hot and cold water as well as air flow measurement in air conditioning
· Medium and large line measurement in general process industry
· Cooling water lines
· Water treatment process
· Pure and ultra-pure water production facilities
· Testing of fire fighting pumps
· Testing of blowers
· Chemical injection
· And so on
Installed flowmeter should guarantee the entry ≥5DN straight pipe section, export straight pipe section not less than 250mm; if the medium containing ferromagnetic material, magnetic filter should be installed in front of the flowmeter. (see magnetic filter and straight pipe section diamension diagram.)
