Tank gauging systems measure the liquid level, temperature, and, if necessary, pressure or density inside the tank, then convert the readings into storage volume or mass and send them to the control room. For tank gauging systems, customers not only requested OEM (original equipment manufacturer) cooperation but also required that the products have ATEX explosion-proof … Read more
This article uses a vegetable oil storage tank 15 m in diameter and 12 m high (about 2,100 m³) as the reference case: a vertical, atmospheric-pressure tank common in grain and oil depots. Vegetable oil is a clean, free-flowing medium, but the tank height and long storage periods make long-term reliability and low maintenance the … Read more
We have provided customized flow measurement solutions for various clients dealing with high-viscosity, low-flow, and corrosive operating conditions. For instance, a polyurethane production line in Nigeria required the metering of a resin with a viscosity of approximately 2000 cP at a flow rate of less than 5 gallons per hour (approx. 19 liters per hour), … Read more
We previously received an inquiry from a user in Mexico requesting a selection recommendation and a quote for an oval gear flowmeter (a type of positive displacement flowmeter). The application involved a DN100 pipe with a flow range of 150–2500 L/min, requiring an accuracy of ±0.2% and repeatability of ≤0.05%. The client had initially selected … Read more
The 3D radar level scanner accurately detects the three-dimensional information of solid materials in silos. Based on 80–140 GHz frequency modulated continuous wave (FMCW) radar, the radar sensor is driven by a rotating and pitching structure to perform a 360° high-resolution scan of the material surface. It generates a 3D visualization image and calculates material … Read more
Sino-Inst supplies 10,000 psi pressure transducers, 1/4 NPT threaded mounting and a 1–5 VDC output. It is suitable for measuring the pressure of gases and liquids. 10,000 psi is equivalent to 68.95 MPa or 689.5 Bar. Benefits Technical Specifications Measuring range 0–10,000 psi Accuracy 0.1% FS, 0.25% FS, 0.5% FS (optional) Output 4–20 mA, 0/1–5/10 … Read more
For reactors, buffer knockout tanks and similar process equipment, operating temperatures tend to run high, and steam together with condensate commonly appear within the vessel gas space. When carrying out level measurement for such units, our preferred instrument option is the 80 GHz radar level transmitter. Regular grade 80GHz radar devices cover process temperatures from -40°C … Read more
Guided wave radar and pressure-based level sensors are common contact-type instruments used for liquid level measurement in industrial storage tanks. Pressure-based level sensors represent a more traditional measurement method; they offer consistently stable performance and are highly trusted by users. Guided wave radar level transmitters utilize newer measurement technology, providing high accuracy and suitability for … Read more
For a project involving level measurement in a sodium hydroxide (NaOH) storage tank, the client had previously used pressure-based level transmitters. Given the corrosive nature of the strong alkaline medium, we recommended an 80 GHz non-contact radar level transmitter; compared to ultrasonic alternatives, this instrument offers superior corrosion resistance and effectively handles in-tank condensation issues. … Read more
For a turbine oil tank level measurement project, the client specified an RF capacitance level transmitter with a 700mm coaxial rod probe and PTFE insulation. The operating conditions are 200°C and 24 bar, with a 4–20 mA + HART output and a 1.5″ BSP threaded connection. An assessment based on application experience confirms that an … Read more
