概述

      JGLUCB plug-in vortex flowmeter is mainly used in various industrial sectors of large diameter pipeline gas, liquid, vapor medium fluid flow measurement, plug-in vortex flowmeter features low pressure loss, scale range, high precision, in Measuring the volume flow rate conditions almost no fluid density, pressure, temperature, viscosity and other parameters. No moving mechanical parts, so high reliability and little maintenance. Long-term stability of the instrument parameters. Plug-in vortex flowmeter sensor using piezoelectric stress, high reliability, can be -20 ℃ ~ +250 ℃ operating temperature range. With analog standard signal, but also digital pulse signal output, easily supporting the use of computers and other digital systems is a more advanced and ideal flow meter。
      JGLUCB plug-in explosion-proof type vortex flowmeter, in line with GB3836-83 "electrical equipment for explosive atmospheres, "the relevant provisions of the explosion logo ExdIIBT6。
Works

    By the International Organization for Standardization IS07145 (circular cross section in the fluid flow in closed conduits determination - that the speed in cross-section method), the use of piezoelectric crystals embedded on vortex velocity probe, inserted into large diameter pipe industry will Karman vortex Frequency conversion with the flow of current or voltage proportional to the pulse signal or 4 ~ 20mADC current signal。
Instrument characteristics

1、 Measurable steam, gas and liquid volume flow and mass flow；
2、No mechanical moving parts, high accuracy, compact and easy maintenance；

3、Pressure loss, wide measuring range; range of degrees of1:25；
4、Eliminate interference with the circuit and the vibration sensor head；
5、Eliminate interference with the circuit and the vibration sensor head, the instrument has a certain resistance to environmental vibration performance；
6、Medium temperature can be measured up to+250℃。
7、Continuous flow can be achieved removable sensor, amplifier and the sensor can achieve separation (separation from 15m)；
