Accurate level monitoring in cement silos is directly related to production scheduling efficiency, inventory management accuracy, and equipment operational safety. This is particularly true in core stages of cement production, such as raw material storage and finished product warehousing. Cement is a dry, powdered material with a low dielectric constant (typically only 1.8–2.5) and high … Read more
LPM, GPM, and m³/h are all commonly used units of volumetric flow rate. They can be converted as follows: 1 L/min = 0.2642 US GPM, and 1 US GPM = 0.2271 m³/h. Different industrial product segments tend to prefer different units. For example, flow meters typically use LPM, while data sheets for U.S. pumps or … Read more
What Is a Differential Pressure Switch? A differential pressure switch is an instrument used to measure the pressure difference between two points. It is classified into mechanical types (such as bellows and diaphragms) and electronic types. When the pressure difference between the two sides reaches a preset value, the sensing element deforms or displaces, driving … Read more
When monitoring the level of warm slurry in an open-top, circular tank approximately 3 meters high, the continuous rise of water vapor often leads to condensation on the sensor surface, which interferes with the instrument’s ability to accurately collect signals. For this specific field condition, we recommend using an 80GHz radar level sensor. Challenges in … Read more
What Is a Paddle Flow Switch? A paddle flow switch is a mechanical flow switch that uses a paddle to detect unidirectional or bidirectional flow of clean media such as air, oil, or water. It is also known as a vane, target, or baffle flow switch. The medium being measured must not contain any entangling … Read more
In a vacuum reactor with a stirrer, the stirrer blade is mounted on the central axis of the vessel; for most of a batch run, the gas phase space remains under vacuum. Many reactors of this type were originally equipped with submersible (hydrostatic) level probes. Under vacuum conditions, these probes present a fundamental problem: common … Read more
Liquid ammonia is anhydrous ammonia that becomes liquid after being pressurized or frozen. Ammonia is an important chemical raw material. For convenient transportation and storage, gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia. Therefore, Anhydrous Ammonia Tank level measurement faces challenges such as low temperature -33.4℃/-28.1 °F, high pressure 0.8~1.5 MPa (116–218 … Read more
FMCW (Frequency-Modulated Continuous Wave) radar level meters, also known as FMCW radar level sensors, calculate the distance to liquid surfaces by comparing frequency differences between transmitted signals and reflected echoes. These devices feature small measurement dead zones and deliver millimeter-level measuring accuracy. Most commercial 80 GHz radar level meters on the market adopt this technical … Read more
Viscosity and its measurement are closely related to experimental scientific research and industrial production. A viscometer is a device capable of effectively measuring the viscosity of a fluid and providing a readout or an output signal. While viscosity measurements were traditionally conducted primarily in laboratory settings, technological advancements now enable such measurements to be performed … Read more
Pressure transducers for ammonia refrigeration are designed to measure the pressure and vacuum of ammonia in both liquid and gaseous states. It is mainly used in refrigeration equipment to measure the pressure of liquid ammonia, gaseous ammonia, or mixtures thereof. It is used for pressure monitoring of ammonia media in refrigeration cycles of cold storage, … Read more
