Features:
(1) Long service life: the normal operation period is up to 15 years.
(2) Wide range: different specifications of the flow meter range of 50:1 ~ 243:1.
(3) high precision, high reliability: measurement accuracy is not affected by media conditions, long-term use does not need to be adjusted.
(4) low starting flow rate: different specifications of the flowmeter's starting flow rate of 0.06m3/h ~ 1.20m3/h.
(5) small pressure loss: different specifications of the flowmeter pressure loss of 0.16kPa ~ 0.55kPa.
(6) structure type more: can choose to use the mechanical counter type (only the total number of working conditions), electronic compensation meter (FCM, temperature and pressure compensation), double display (mechanical counter + electronic compensation meter).
Flow meter compensation function
(1) Real-time volume compensation: real-time measurement of temperature and pressure, calculation of compression factor, automatic compensation to the standard state.
(2) Micro power consumption: built-in battery can be used for more than 5 years. When connected to external power supply, the built-in battery is automatically disconnected.
(3) Diversified output interface signals: three pulse output methods, two-wire or three-wire current 4-20mA output, three RS485 communication protocols.
(4) Data logging function, record the flow process state parameters, can be read through the RS485 communication query.
(5) Multi-physical parameter alarm function. Flow, temperature, pressure can be set to exceed the upper and lower limits of the alarm.
(6) Intrinsically safe explosion-proof ExiaIICT4, shell protection grade: IP65.
Applications:
Roots flowmeter, its accuracy and stability is very good, the outstanding advantages of this flowmeter measurement of natural gas are: starting low flow rate at the beginning of the process is relatively wide; for frequent intermittent use of natural gas users; not subject to the electromagnetic signal interference with the site flow value is very accurate; without the need to reserve a straight section of the measurement accuracy is not affected by the length of the pipeline straight section; a long time to use the no-maintenance and service life of up to 15 years!
