The KF Series of Field Mounted Indicating Controllers, which the special manufacturing techniques is introduced from Japanese Yamatak-Honeywell Co., Ltd, provides both application flexibility and instrumentation savings by employing a common type of indicating control section in each instrument. All process variables, such as temperature, pressure, level and flow, can be measured and controlled by the same type of instrument. The difference is only in the detector. Thus, the KF Series provides model simplicity and uniformity, and requires very little in the way of maintenance.
The KF Series comprises not only Indicating Transmitters but also Indicating Transmitting Controllers. They are united in structure, and combined in functions, complete in varieties and specifications with stable performance, high precision, strong anti-interference ability, high reliability, and are easy to mount and maintain. They are intrinsically safe and explosion-proof, able to drive the pneumatic performance mechanism directly, so they have been generally well accepted and trusted by domestic and foreign customers.

Model KFT Temperature Indicating Controllers indicate and control a process variable by converting its temperature change into mechanical displacement of a bellows through change in expansion of liquid-fill by temperature or change in gas-fill pres-sure by temperature.

Sanitary Vs. Standard Electromagnetic Flow Meters
d and beverage processing. Choosing between sanitary and standard models can significantly impact cost, compliance, and operational efficiency. This guide helps you select the right flow meter for your facility, whether you need an electromagnetic flow meter for beer, pure water, or jam, or a food grade flow meter for dairy and beer.

Key Requirements for Food-Grade Flow Meters
Food and beverage applications require hygienic electromagnetic flow meters that meet strict hygiene and safety standards:

Hygienic Design

3-A Sanitary Certification: Ensures smooth surfaces (â?¤0.8 �µm roughness) with no crevices to prevent bacterial growth.
FDA-Compliant Materials: PTFE or PFA liners and 316L stainless steel electrodes prevent contamination.
CIP/SIP Compatibility: Withstands high-temperature caustic cleaning cycles.
Material Safety

Non-toxic, non-absorbent materials.
No lubricants or seals that could harbor pathogens.
Performance in Low-Conductivity Fluids

Advanced models with â??Signal Boostâ?? technology can measure low-conductivity liquids like milk (~500 �µS/cm).
Ideal for applications requiring a conductivity meter for food and beverage or a food grade electromagnetic flow meter.

liquid mass flow meter

Coriolis Mass Flowmeter (abbreviated as CMF) is a high â?? precision flow instrument that directly measures the mass flow of fluids. It operates based on the principle of the Coriolis Effect. It can not only measure mass flow but also simultaneously obtain parameters such as density and temperature, and is widely used in fields such as petrochemical, food and medicine, and energy metering.

Working Principle
Coriolis Effect
When the fluid flows through the vibrating measuring tube, a Coriolis Force is generated, causing the measuring tube to undergo a slight deformation. By detecting this deformation, the mass flow of the fluid can be calculated.



Measuring tube vibration: The electromagnetic drive makes the measuring tube vibrate at its natural frequency.
Phase difference detection: When the fluid is flowing, the vibration phase difference between the inlet and the outlet is proportional to the mass flow.
Density calculation: The vibration frequency of the measuring tube is related to the fluid density, enabling synchronous density calculation.

MAG7000 Flow Meter
https://www.leestransmitter.com/products/7000electromagnetic-flowmeter/

An electromagnetic flow meter (mag meter) measures the flow rate of conductive liquids using Faradayâ??s law of electromagnetic induction. When a conductive fluid flows through a magnetic field, it generates a voltage proportional to the flow velocity, which the meter converts into a flow measurement.

Key Features of MAG7000 Flow Meter
Non-intrusive measurement â?? No moving parts, reducing maintenance.
High accuracy â?? Typically �±0.5% of flow rate.
Suitable for various liquids â?? Works with water, slurries, acids, bases, and beverages.
Bidirectional measurement â?? Can measure flow in both directions.
Wide pipe sizes â?? Available from small to very large pipelines.
Selection of installation site
The measuring tube must be fully filled with medium at all times â?? electromagnetic flowmeters cannot operate normally when the tube is not full or empty.
1) Select a straight pipe section filled with liquid, such as a vertical section of the pipeline (the flow direction is preferably from bottom to top) or a horizontal pipe filled with liquid (the lowest point of the entire pipeline is the Xuan). During the installation and measurement process, non-full pipe conditions must not occur.
2) The measurement position should be selected at a location greater than 5D upstream of the flowmeter and a straight pipe section of 3D downstream.
3) The measurement points should be selected as far away as possible from pumps, valves and other equipment to avoid their interference with the measurement.

4)The measurement points should be selected as far away as possible from large radio frequency, strong magnetic fields, strong vibration interference sources, etc.
