Features
Calculates snap and accumulated volume and flow rate of liquid;
Inputs liquid density value using keyboard of measuring and computing unit;
Calculates product weight corresponding to snap and accumulated volume;
Displays calculated values;
Switches off the flow meter when the pipeline is not filled with liquid.
Application
Designed for measuring volume and flow rate of milk, cultured milk products and other edible liquids.
The device is designed as an integral resident measuring and computing module. Different installation variants are provided. Optionally the milk flow meter can be supplied with a thermal converter and a pressure transducer with standard DC output 4−20 mA.
Operating principle
The operating principle of the flow meter / counter is based on the electromagnetic induction phenomenon. As conductive liquid is passed through the magnetic field, an electromotive force proportional to the average velocity of the liquid is induced in it since the liquid acts as a mobile conductor.
The electromotive force is taken off by two electrodes which are positioned in diametrically opposite directions in one transversal section of the pipe in the primary flow transducer flush on the inner surface. The signal from the primary flow transducer is sent over the shielded wires to the input of the measuring unit for further processing.
Advantages
- High-precision measurement of flow rate, volume and mass of liquids
- Wide dynamic range of flow rate measurements
- Automatic detection of absence of liquid in the pipe
- Dosing function
- Small straight pipe length ((5DN-3DN)
- Temperature and pressure monitoring of liquid being measured
- Large volume of statistical data on the parameters of liquid being measured
- Data can be transmitted to the PC via the RS-485 interface at a distance up to 1 km
- Tens of flow meters/counters for the food industry can be merged into a network via the RS-485 interface
- A printer can be connected via the parallel interface
- No hydraulic resistance of electromagnetic flow meters
- Ease and comfort of assembly and operation
- Low power consumption
