LEFM® technology was installed on the first petroleum application in 1972. By 1976 a leak detection system in Alaska using 48 inch LEFM meters was installed and continues to operate today.
Caldon played a key role in establishing the API standard for measuring liquid hydrocarbons with transit time ultrasonic flow meters.
LEFM Series 200 flow meters are used in all areas of Petroleum processing - gathering, production, and distribution - by companies all over the world. The SoundTrack system is used to measure the relative density and kinematic viscosity of petroleum fluids.This information can provide interface detection in pipelines that carry multiple products.

deltawave - Ultrasonic multimeter for fluids
Our new measuring system deltawave is not only a precise flowmeter for open channels,filles and partially filled pipes but also a temperatur meter and a flow profile analysis tool. Due to the unique patent pending signal analysis deltawave works under extreme conditions, maintenance-free, calibration-free and reliably. The measurement system monitors itself continously and the multi-channel property ensures redundant safety. With only one deltawave, you can realize up to four independent measurement sites, significantly reducing the equipment cost. This feature, combined with the high accuracy up to 0.5% makes deltawave to one of the most powerful measuring systems.
Because of the high accuracy, field acceptance tests of hydraulic turbines, storage pumps and pump-turbines are possible due to ISO60041 and ASME PTC 18. Accuracies up to 1% could be achieved in open channels without calibration. In filled pipes or channels you will get an accuracy of 0.5% of reading. But measuring with deltawave do not means only accuracy. The optimized transducers ensures long-term stable measuring without maintenance. This has been proven successfully by public authorities.

Clamp-on ultrasonic flowmeters
The SITRANS F US clamp-on ultrasonic flow technology offers several advantages, number one being the utilization of external transducers. These are quickly and easily mounted on the outside of the pipe, making them the perfect choice for retrofit applications and applications where corrosive, toxic or high pressure liquids and gases rule out the option of cutting the pipe.
With the use of the WideBeam technology, clamp-on flowmeters from Siemens have proven their superiority in both the field and the lab. They offer several benefits such as measurement of practically any liquid and gas; performance unaffected by viscosity, flow rate, pipe size, solids and aeration content; high accuracy and repeatability through automatic temperature compensation and zero drift correction; and installation flexibility on pipe sizes up to DN9140 (360 inches). They are available in six families: two geared towards general industry solutions and four tailored to energy, liquid hydrocarbon, gas and portable installations.
Combine this with flexible configuration options that allow you to either customize your flowmeter or to order complete systems, you can rest assured that we have the right solution for you.

Clamp-on Ultrasonic Flowmeter with DSP Technology
The MUL-310 is a "Time of flight" type Ultrasonic Flowmeter for liquids. Since the ultrasonic receiver required for the flow measurement is installed by the clamp-on system on the exterior of the pipe, it does not contact the measuring fluid at all, and also there are no concerns about particle generation or contamination of metallic ions in the fluid as it is truly non-invasive. It is suitable for the flow rate measurement of pure water and ultra pure water for the semiconductor industry. The resistance to bubble interference in the signal has been sharply improved by the new signal process method "DSP"(Digital Signal Processor). If bubbles are contained in the fluid, the transmission of the ultrasonic signal is impeded and signal recognition becomes difficult resulting in a loss of signal. Digital Signal Processing technology has been adopted for MUL-310, and even if the bubbles are contained in the fluid, the stable measurement of signal can be achieved. This product does not have limitations in terms of volume of bubbles by air volume being less than 10%. (It is not possible to recognize the signal in case of fluid streams with excessive bubbles)
