Micro circular gear flow sensor-SN54B

Product introduction

SN54B gear flow sensor built-in double circular gear operation, through the high-precision gear volume calculation of the media through the volume, to achieve the measurement of micro-fluid media. It is a new type of volumetric flow sensor. Used for precise continuous or intermittent measurement of liquid flow or instantaneous flow in pipelines.
-Pulse / 4-20mA analogue option.
-High pressure resistant (1.0-45MPa)
-High and low temperature resistance (-40...150° C). .150° C)
-Measurement of various viscous media
-High accuracy and repeatability
-Wide range ratio (1:100)
-Wide measuring range
-Anti-corrosion and high dirt resistance (acid and alkali)

SN54B Gear Flow Sensor is widely used in various industries for accurate measurement of low flow rates. Applicable media: additive fuels, flotation tanks for water treatment, corrosion inhibitors, catalysts, emulsifiers, oils, greases, fragrances, adhesives, solvents, inks and pesticides, and other partially high-viscosity media. Applications include automotive, aviation, mining, power
Air, mining, electric power, chemical, pharmaceutical, food, paint, petroleum, environmental protection, printing and other industries.
Especially suitable for heavy oil, polyvinyl alcohol, resin and other viscosity of the media flow measurement (can measure the viscosity of up to 10,000 Pa.s fluid). Volume, light weight, low vibration and noise during operation and stable operation, can also be used to measure the small pipe diameter of the measurement of the micro-flow. Starting flow rate of small range ratio is wide, suitable for measuring the flow of liquids in line with the large changes in the measurement accuracy is not affected by changes in pressure and flow rate, stable performance, long life, large flow capacity.
-Resin, glue measurement
-Measurement of hydraulic oil, lubricating oil and grease.
Fuel oil measurement
-Measurement of liquid nitrogen, freezing liquid and solvents.
-Measurement of edible oil, fish oil, and food filling
Measurement of chemical and anti-corrosion fluids
-Fluid dosing control system
