Used extensively to measure volumetric flowrates of electrically conductive liquids or slurries, electromagnetic flowmeters offer maintenance free function due to the lack of any moving parts. The fact that these meters have no obstruction to flow in the form of probes or turbines ensures no pressure drops across meter. By making use of Faradays laws of magnetic induction, the meter can measure the emf produced when conductive liquid flows through the meter-created magnetic field.

Having the unique feature of not having any obstructions to flow, electromagnetic meters have been used to take advantage of this fact to handle various liquids with solid particles like sewage and milk. Here are a few applications:

• Sewage treatment plants
• Sugar Syrup
• Coal Slurry
• Hard water
• Beverages
• Alkalis and acids

Toshniwal Turbine Flow Meters / Axial Turbine Meters measure volumetric flow rate directly by translating the mechanical action of rotating turbines placed in fluid stream into user readable fluid flowrates. The accuracy of Turbine flow meters depends largely on the flow and velocity profile of the fluid flowing through it. The meter is available in either SS304 or SS316 construction.

• Line Size Ranges: 4mm to 200mm
• Power Supply: Battery / 24VDC Power Supply

The DIMF series density/concentration meter is based on the oscillating element principle. The fluid to be measured flows through the oscillating element (a tuning fork for Type 1.3 and an oscillating tube for type 2.0) that is excited electromagnetically and will oscillate at its natural frequency. Changes in the density of liquid passing through will lead to changes in the oscillating frequency. Electronic transducers pick up these frequency changes and convert it in to a signal that is proportional to the density or concentration of liquid.

• Density Range: 0 to 5g/cm3
• Operational flow rate ranges: 0 to 50 l/min
• Measured variable available in standard 4-20 mA output signal or HART communication protocol
• Direct measurement of density, reference density or concentration
• Robust construction leads to long life and high reliability
• Very high accuracy and repeatability
• Simple installation
• Resistant to vibrations and pressure changes or flow rate changes

Major applications for DIMF series are process control and quality monitoring of fluids in all areas of industry. The device can be used for density mass flow conversion for custody transfer in connection with corresponding volumetric meters and flow computers.

Toshniwal portable Transit Time flowmeters measure liquid flowrate by calculating the spreading time of ultrasonic wave downstream and upstream of liquid in pipe. This is done by using clamp-on sensors which non-intrusively generate and receive ultrasonic waves. The flow meter is most suited to measure homogeneous fluids with very low percentage of suspended solids and gas bubbles.

• Water treatment facilities, Slurry and waste water pipes
• Used for challenging liquid flow measurements like acids and alkalis
