In-line viscometer(For High precision) FEM-1000V Series Catalog


Detect viscosity of the liquid by the change of the vibration.
Using a piezoelectric acceleration sensor, and achieve high resolution.
It is a revolutionary product that uses the resonance phenomenon.

By adopting an oscillator with an unique balanced structure, we have achieved the long-term reliability and stable viscosity measurement.

Patented (Japan, U S and UK)

Summary

FEM-1000V is a torsional oscillation viscometer of inline process applications.
You can measure the viscosity and temperature in real time and continuously by attaching tank or pipe with the flange.
It is a maintenance-free viscometer due to using a piezoelectric ceramic in the driving unit.
Viscosity sensor portion (probe) has become a full sealed structure, non-explosion proof type is also possible to soak in the liquid the entire probe addition to being attached with the flange.
It is possible to viscosity measured in flow state of liquid by attaching to the pipe that the flow of the liquid and the tank is agitated.
Explosion-proof type holds a flameproof, you can use in the controlled area with confidence.

Feature

Viscosity measurement accuracy is within ± 1% of measured value.
This means that the measurement accuracy is within 1% that even a 800mPas even 1mPas.
Probe is waterproof and dustproof structure compact and robust. In addition, it is made of stainless steel resistant to corrosion.
Also, because the wetted parts are welded all,it is superior to confidentiality and excellent washability.
The viscometer measures with high accuracy(±1% of measured value)by adopting bidirectional balanced oscillator(patented)without being affected by vibration process.
The probe can be set vertically,horizontally or obliquely to the flow direction.
It does not have to require installation adjustments to the distortion or the like mechanical stress at the time of installation.
Measured viscosity data of high measurement accuracy within ±1% of the measured value is possible to output through 4-20mA (analog output),or RS232C (digital output). Therefore, it is the optimum viscometer for production management for automation line.
Flameproof compliant standards are as follows.

The oscillation frequency of Controller with PLL circuit is always controlled to equal the resonance frequency of the vibrator.
It measures viscosity accurately even when the resonance frequency of the vibrator changes due to effect of temperature.

Usage

Decentralization and Dispersion
Management of ink, paint, various coating, and film formation
Slurry, Food

The principle and structure



Our viscometers are torsional oscillation, constant shear stress systems driven by a piezoelectric ceramic source as actuator.
It vibrates,in the direction of rotation.2 identical inertial masses(drive part I1 and detector I2)at the both ends of the torsion rod of vibration unit.
The system measures viscosity resistance at a viscosity detector as the amplitude of vibration by acceleration sensor located at the upper mass and converts it into viscosity.
The node of the resonance in the center of the torsion rod (node:patented)is the non-moving point, and the upper and lower inertia mass(I1, I2)vibrates in an oppsite direction each other(the bidirectional balance type oscillator).
It does not matter the installation location of the probe by Node and also an installation adjustment by the mechanical stress distortion when installing, isn’t required.
A torsion rod is welded to a base of a probe housing through atorsion pipe, and it is the perfect sealed structure.

Options


Applicable to sticky slurry, strong acid, strong alkali.

Various Ferrule sizes are available

It is one of the ways when you are installing a viscometer to pipe in food lines, etc.

The guard is installed to protect detector from scratches,bend and etc. by the hard pieces not to dissolve in the liquid.
Guard does not influence any effect on the viscosity measurement.

FEM-1000V series Installation Examples.

The detector can be installed at any angles of Flow due to adopt the balance type vibrator with piezo electric ceramics as a driving source.
