  • Level Meter Price & Quote Request

    Most buyers open a sourcing conversation with one line: “how much is a level meter?” The honest answer is that the price of a level meter is not a number you can quote from a catalogue, because a level meter is not a single product. It is a measurement system assembled around your med...

  • Measuring Liquid Nitrogen with Guided Wave Radar: A Cryogenic Case Study

    Measuring Liquid Nitrogen with Guided Wave Radar: A Cryogenic Case Study

    One semiconductor fab in East Asia kept its liquid nitrogen (LIN) inventory on a 50 m³ vacuum-insulated storage tank, feeding cryo-pumps and a thermal-shock test line that ran the metal packages down to −196 °C before they ever reached a wafer. The tank was measured by a differential-pressure (DP...

    Case Study: Ultrasonic Level in Chemical Storage Tanks

    A mid-size chlor-alkali and specialty chemical plant in southern China ran its tank farm on magnetostrictive float gauges and wet-leg differential pressure transmitters for eight years, and by year seven the maintenance log read like a confession. Float stems seized in viscous caustic, differenti...

  • Radar Level Meter Selection Guide

    Radar Level Meter Selection Guide

    Radar level meters look simple on the shelf until the beam clips an agitator shaft and the reading locks to the wall, or until condensation beads on the antenna and the display starts tracking a phantom surface two metres above the liquid. We build these instruments, tune their signal processing ...

  • Ultrasonic vs Radar Level Meter: Which to Specify

    Ultrasonic vs Radar Level Meter: Which to Specify

    Pick the wrong level technology and you will be climbing the tank again in six months, this time with a calibration laptop and a maintenance work order instead of a tape measure. We build both ultrasonic and radar level meters on the same production floor, calibrate them against the same traceabl...

  • Cryogenic Guided Wave Radar Level Transmitter: Field Notes from the Cold End

    Cryogenic Guided Wave Radar Level Transmitter: Field Notes from the Cold End

    A liquefied natural gas vessel sits at minus one hundred sixty-two degrees. A liquid nitrogen dewar at a wafer fab runs near minus two hundred. At those temperatures ordinary level instruments either freeze their seals, lose their echo in a steam that is not air, or simply cannot see an interface...

  • Ultrasonic Level Meter for Storage Tanks: Field Notes from the Bench

    Ultrasonic Level Meter for Storage Tanks: Field Notes from the Bench

    A storage tank is a quiet liability. It sits there full of diesel, caustic, or finished water, and the moment nobody can tell how full it is, a transfer pump runs dry, a bund overflows, or a batch gets blended against the wrong inventory. We put ultrasonic level meters on tanks because the sensor...

  • Flow Meter Manufacturer & OEM/ODM in China: What an Integrated Builder Actually Controls

    Flow Meter Manufacturer & OEM/ODM in China: What an Integrated Builder Actually Controls

    When a buyer searches “flow meter manufacturer,” the word that should matter is integrated. Most listings on that search are trading companies with a logo and a price sheet; the instrument was never near their bench. We are not that. LONNMETER is a research, manufacturing, and sales g...

  • Flow Meter Price & Quote: What Drives the Number, and How to Get One

    Flow Meter Price & Quote: What Drives the Number, and How to Get One

    Most buyers start a flow-meter project with one question: how much does it cost? The honest answer is that a flow meter has no single price. The same nominal bore quoted by two suppliers can land three times apart, and both can be right — because the number is built from a stack of engineering ch...

  • Electromagnetic Flow Meter Selection Guide

    Electromagnetic Flow Meter Selection Guide

    A magmeter looks simple until you have to size one for a slurry that chews through linings, or a dosing line where the electrode plates over in a fortnight. We build these instruments, calibrate them on our own water benches, and watch them fail in the field when the lining or the ground path was...

  • Coriolis Mass Flow Meter Selection: Sizing, Fluid Fit, and the Decisions That Actually Matter

    Coriolis Mass Flow Meter Selection: Sizing, Fluid Fit, and the Decisions That Actually Matter

    You do not specify a Coriolis mass flow meter by model number. You specify it by answering a short list of ugly questions about your medium, your pipe, and the figure on the batch report that someone will eventually dispute. We machine the tubes, weld the headers, and calibrate every transmitter ...

  • Electromagnetic Flow Meter for Water & Wastewater: Application Note

    Electromagnetic Flow Meter for Water & Wastewater: Application Note

    A water utility does not buy a flow meter because it is elegant. It buys one because the number on the screen has to hold up in a billing dispute, survive a grit-laden storm overflow, and still read within tolerance after five years of chlorinated water. We build magmeters for exactly that kind o...
