high pressure air flow meter, Integrated orifice flowmeter for satuated steam,Pipe size DN15-DN800 mm

General introduction

The configuration of ordinary differential pressure transmitters and ordinary flow display device integrated throttling flowmeter in the flow or pipe conditions change, without the replacement of throttling case, the use of "LG-94-01 version of the throttle Device design computer management software "to recalculate outflow coefficient C, coefficient of expansion ε, full-scale differential pressure value (or full-scale flow value), to modify the flow display device settings and adjust the differential pressure transmitter range. An intelligent, differential pressure transmitter with an integrated throttling flowmeter enables wide-range detection. Flow measurement up to 10: 1 or wider.

Integrated throttle flowmeter and differential pressure transmitter into one. Differential pressure transmitter and flow display device through the analog signal (4 ~ 20mA) or digital signal (HART protocol) communication, constitute the flow measurement system. The system uses digital integrated throttle flowmeter communication (HART protocol) flow measurement range up to 10: 1 or wider. The integrated throttling flowmeter inherits the medium to adapt to the throttling medium (liquid, gas, steam, general), no moving parts, without the actual calibration (can be measured using the geometric dry method), high temperature and pressure, impact resistance is not easy Deformation and other advantages. At the same time, the system design of antifreeze isolator, instrumentation department need insulation, with heat and condenser, the structure is more reasonable, easy to install, greatly reducing the amount of maintenance. Due to the use of antifreeze isolator greatly reduces the length of the lead tube, low failure rate, good dynamic characteristics.

Product features

• Stainless steel pipe flow resistance components, the pressure loss can be low.
• can measure most of the media flow.
• multi-parameter display: show the flow and differential pressure and pressure.
• According to user needs to change the flow range online.
• high measurement accuracy, wide measurement range up to 1:10, to meet the trade settlement requirements.
• Optional welding structure, measuring high temperature and pressure medium flow measurement.

Mounting notice:

The installation of the throttling device is suitable for the following pipe sections and pipe fittings: the first resistance element on the upstream side of the throttling member, the second resistance element, the first resistance element on the right under the throttling element, the second resistance element on the upstream from the throttling element Downstream of the first resistance between the pipe section and the differential pressure signal pipeline. The main need is based on the measurement medium to choose a suitable way of measuring the pressure tube and a sufficient length of straight pipe before and after.

Technical data

Structure

• Throttle: standard orifice, standard nozzle, long diameter nozzle, 1/4 circular orifice plate, double orifice plate, eccentric orifice plate, round orifice plate, conical inlet orifice plate and other pressure device: Flange, clamping ring, pressure pipe and other connecting flange (national standards, various standards and other design sectors of the flange), fasteners. Measuring tube.
• Orifice flowmeter installation requirements: The requirements of the straight pipe is generally 5d after the first 10D, so in the purchase of orifice flowmeter must be based on the situation of the flowmeter on-site industrial and mining to choose for the scene of mining flowmeter.
• The fluid filled pipes, as they flow through the throttling device in the pipeline, will locally contract at the throttling element of the throttling device so that the flow rate is increased.
