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
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
In industrial tank level measurement applications, high-performance guided-wave radar level transmitters—such as the Eclipse 706-512B-320—have become the ideal choice for many high-precision operations due to their stable measurement performance. The 316 stainless steel model, in particular, meets the measurement requirements for the majority of standard industrial media. Unlike the simple selection process for general-purpose instruments, … Read more
A water pump is a device used to transport or pressurize liquids. Pump head refers to the height to which the pump can lift water; pump head is directly proportional to pressure. Based on clear water at 4°C (39.2°F), density 1000 kg/m³: 1 psi = 2.31 ft H₂O = 0.703 m H₂O; 1 ft H₂O … Read more
On-site flow measurement for large-diameter pipelines is often constrained by requirements such as water supply shutdowns or the need to cut into the pipe, making flexible operation difficult. For pipelines with a diameter of DN1600 or larger, handheld ultrasonic flow meters utilize a non-invasive, clamp-on measurement method; this allows flow to be measured directly from … Read more
Pressure sensors can operate with media temperatures of 450°C. It is important to clarify that this refers to the temperature of the medium itself, not the ambient temperature. Standard pressure sensors typically measure media temperatures in the range of -20°C to 80°C. Custom high-temperature pressure sensors can measure pressures in media at 450°C; however, the … Read more
