ELECTROMAGNETIC FLOW METERS
Toshniwal electromagnetic flowmeter accurately measures the flow rate of electrically conductive liquids or slurries flowing in closed pipes. Known for performance and robustness, the electromagnetic flowmeter is obstruction less and hence does not add pressure drop across the meter. As there are no moving parts, they are maintenance-free. By making use of Faraday’s laws of magnetic induction, the meter can measure the EMF produced when conductive liquid flows through the meter-created magnetic field. The performance of the electromagnetic flowmeter is not affected by the corrosiveness, viscosity, and density of the liquid measured.
V CONE FLOW METERS
V-Cone Flow Meter is an advanced differential pressure flow meter technology is ideal for measuring a variety of flow media in various states and temperatures. From Mccrometer V-Cone Flow Meter can be used for measuring liquid, steam, or gas media in rugged conditions where accuracy, low maintenance, and cost are important.

TURBINE FLOW METERS
Toshniwal Turbine Flow Meters are known for their longevity and reliability. They are extensively used for measuring low viscosity liquids that flow inside pressurized closed pipes. The Turbine Flow Meters /Axial Turbine meters measure volumetric flow rate directly by translating the mechanical action of rotating turbines placed in a fluid stream into user readable fluid flow rates. The accuracy of the turbine meter depends on the flow and velocity profile of the fluid flowing through it. The liquid turbine flow meter is available in either SS304 or SS316 construction.
DENSITY METERS FLOW METERS
Known for long service life and high reliability, Density Meter from Bopp & Reuther gives a highly accurate reading. 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. An electronic transducer picks up these frequency changes and converts them to a signal that is proportional to the density or concentration of liquid. Our density measuring instruments have robust construction. Our Density Meter Ensures Higher accuracy and repeatability, Operator independent results, Improved efficiency, Trustworthy data quality. We at Toshniwal offer the best density meter that suits the need of your business.
VORTEX METERS FLOW METERS
Their vortex flow meter is ideal for measuring high flow rates of liquids, where moving parts of the equipment present challenges. Microprocessor-controlled Vortex meters measure the high flow rate of liquid with excellent compensation of vibrations and metrological characteristics. These meters work on the principle of the Karman vortex street. Their vortex flow meters are designed to be extremely rugged and stable. The modern and user-friendly microprocessor-controlled electronics come with auto-adaptive digital signal processing.
CORIOLIS INDUSTRIAL MASS FLOW METERS
This meter utilizes the Coriolis force for flow measurement. The omega loop has proven itself particularly suitable for this process. The measuring tubes, which are bent to omega loops, are completed by two measuring bars and vertically secured torsion bars to create a harmonious oscillator. This carefully balanced and robust design has an extremely low power input. The frequency of the system essentially depends on the mass of the bars and the elasticity module of the torsion bars. Two electromagnetic coils set the system in motion. As soon as liquid or gas flows through the oscillating omega tubes, the resultant Coriolis force causes displacement of the tubes. The comparative relationship is established and the change in displacement is proportional to the mass flow.

In this spirit, we have partnered with Roediger Systems from Germany to bring this Vacuum Sewage System to India. The vacuum Pumps are used in centralized locations to suck Sewage from source to Treatment Plants. By using Vacuum pumps and the differential pressure that they create to transport sewage over a long distance, we are able to eliminate the need for Sloping Gradient pipes, pumping stations, and enormous quantities of water to drive the sewage over long distances.
POWDER MIXERS
SINGLE SHAFT PADDLE MIXER
The Toshniwal Single Shaft Powder Mixer is an ideal solution for high throughput, economical mixing and meant for adding shear. The unique single paddle design divides the housing into zones each served by at least two paddles. All moving particles create a dynamic interaction between the zones. Voids are created mechanically and particles are directed to randomly fill the voids. The high volume of voids created achieves the speed of mixing. Accuracy is achieved by limiting the size of the void so particles do not roll apart.
TWIN-SHAFT PADDLE MIXER
The Toshniwal Twin Shaft Powder Mixer is the industrial standard for any application that requires mixing 2 or more powders homogeneously. The unique design of Toshniwal Twin Shaft Paddle Mixers enables us to guarantee a homogeneous powder mix to our clients, in very quick cycle times. We understand the critical importance of an even, repeatable mix for our clients in reduced mixing times. Our Twin shaft paddle mixer is our solution for this exact requirement. The Twin Shaft paddle mixer has two counter-rotating shafts with welded paddles. The paddles lift the material up in the center of the mixer in weightless whirls, creating ‘’fluidization”. The particles have total freedom of movement and fall into each other, ensuring the highest level of homogeneity. The movement of paddles ensures convectional transport of particles along with the mixer, while the lift and fall of particles help them to diffuse into each other in a very short span of time.
PADDLE SHAFT MIXER DRYER
Toshniwal Paddle Shaft dryers are built around our very successful and widely used Twin Shaft Paddle Mixer design. Open type variants and Closed type variants are available. The Open System is designed in such a way that makes ambient air blow into the drying system. The air warms up in a heater before blowing into the drying chamber. The hot air is inserted on both sides towards the paddles in the dryer. The paddles bring the air through the material, up to the fluidized zone where the particles can be lifted to create a larger surface area to increase the drying rate. The moist air is blown out of the dryer with fine particles which collect in the filter bags, kept in the exhaust side of the dryer. Close System has the heated air blown into the mixer along with the moist product. The heat exchange makes the moisture evaporate from the product. Moist air passes through the filter before it is sucked into the fan. The air is then blown through the cooler for condensation before it is reheated. When drying very moist products, the wet product is mixed with dry first, to ensure that the fluidization and the high drying rate are maintained.
ROTARY CONE VACUUM DRYER
The Toshniwal Rotary Cone Vacuum Dryer is the perfect solution for drying temperature-sensitive powder products. The Toshniwal Rotary Cone Vacuum Dryer is a result of a collaboration between our Process Powder and Process Vacuum teams. With decades of experience in catering to the pharma and chemical sector in India, our Vacuum engineers have contributed to the design of this product. The jacketed (Double-walled) Cone chamber with desired drying medium like hot water, steam, or Oil is in a constant rotary motion to expose maximum drying surface to powder product. Coupled with Toshniwal Vacuum pumps, we are able to achieve a homogeneous and dry powder product in relatively short cycle times.
POWDER TRANSFER SYSTEM
Transporting large volumes of hazardous or sensitive powders and granules across large distances and heights is a challenge as normal conveying systems like bucket elevators or screw conveyors are out of the question. For such special cases, Toshniwal’s Process Powder division and Process Vacuum Division engineers have come together to develop a very effective Powder Conveying System using Vacuum. The innovative powder transfer system is used to transfer from almost every receptacle or machine and be charged into any type of receiver. The system allows the powder to be charged directly into Mixer / closed hopper/vessels etc. in a totally safe way preventing dust formation. The system can be retrofitted/integrated into an existing production line. The biggest advantage of using the system is that the energy consumption is very low.
