HKLQ Gas roots flow meter

high accuracy intelligent natural gas roots flow meter

/ Product Description /

HKLQ Intelligent Gas Roots Flowmeter is a kind of gas monitoring and measuring instrument with high precision, high reliability and wide range.Intelligent Gas Roots Flowmeter is a new type of flowmeter that integrates flow, temperature, pressure sensors and intelligent instruments on the basis of Waist Wheel Flowmeter.

Main features of the product:

♦ Wide range:

   According to different specifications, the highest range can reach 1: 216

♦  Low initial flow:

   According to different specifications, the minimum starting flow can reach 0.04 m3 / h.
   Long - term precision is not affected by medium, long-term operation and stable precision.

♦ Pressure loss is small:

   According to different specifications, the pressure loss is 0.08 kPa - 0.58 kPa.
   High integration and low power consumption:
   Using advanced microcomputer technology and high performance integrated chip, the whole machine has powerful functions and superior performance.

♦  Compact structure:

   Pressure sensor, temperature sensor and flow sensor are all built in, making the structure more compact.
   Digital pressure and temperature sensor:
   Digital temperature sensor and digital pressure sensor are configured, calibrated and verified separately, and easy to replace, maintain and use.

♦ Subparagraph correction:

   According to the flow frequency signal, the instrument coefficient can be automatically corrected in six sections to improve the wide range accuracy of the instrument.

♦ Full data storage capabilities:

This flowmeter carries out the measurement technical specifications and standards of JB / T 7385 - 1994 " Gas Roots Flowmeter" and JJG 633 - 2005 " Verification Regulation of Gas Volumetric Flowmeter" and conforms to the national standards GB 3836.1 - 2010 " Explosive Environment Part 1: General Requirements for Equipment" and GB 3836.4 - 2010 " Explosive Environment Part 4: Equipment Protected by Intrinsically Safe" I "

♦ 3.2 Accuracy Level:

   Level 1.0: qmax - 0.2qmax 1.0 % 0.2qmax – qmin 2.0 %
   Level 1.5: qmax - 0.2qmax 1.5 % 0.2qmax - qmin 3.0 %
   If the products are not specifically indicated, they will be shipped with a precision of 1.5, and the rest will be customized with special instructions when ordering.

/ Product Application /
