Product Description

Electromagnetic flowmeter/ water flow meter/ mass flowmeter/ liquid flowmeter
Electromagnetic flowmeter is a new type of flow measurement instrument.
Based on the electromagnetic induction principle, it measures conductive liquid flow according to electromotive
force induced by the conducting flow going through the applied magnetic field.
It is used to measure the conductive liquid flow of tap water, steel, petroleum, chemical, electric power,
industry, water conservancy and other departments, and can also measure the acid, alkali, salt and other
corrosive conductive liquid.

Tianjin U-ideal LDG electromagnetic flow meters are intended for fluid measurement in most industries including water, wastewater, food and beverage, pharmaceutical and chemical.
There are two basic components of electromagnetic flow meter: 1)The Detector, which includes the flow tube, isolating liner and measuring electrodes, and 2) The Converter, which is the electronic device responsible for signal processing, flow calculation, display and output signals.

The materials of construction of the wetted parts (liner and electrodes) should be appropriate for the specifications on the intended type of service. Review of the compatibilities consistent with the specifications is recommended.

All electromagnetic flow meters are factory tested and calibrated. A calibration certificate is included in the shipment of each meter.

1 Feature and Application
The electromagnetic flow meter works according to Faraday Law, the
Flow meter is used to measure volumetric flow rate for inductive liquids and pulps. This type Electromagnetic flow meter has several characteristics.
The measurement is independence of the density, viscosity, temperature, pressure and conductivity of the measured fluid.
No moving parts in the measuring tube. No pressure loss. Low requirement for the upstream and downstream straight pipes.
All digital processing, high disturbing resistance, reliable measurement, high accuracy, wide measuring range up to 1500: 1;
The transmitter uses a 16 bits Embedded microprocessor, easy to operate, displays measured values in Chinese, has self-test and self-diagnosis function.
Dual direction measurement function. It can display forward direction flow rate and reverse direction flow rate. It can also display dual direction of current and frequency output, easy to record and save the signal for different direction.
Three inside counters can respectively display forward direction volume,
Reverse direction volume and the different volume of both directions.
It is possible to communicate via RS485 or RS232.
1.2 Main application range
It can measure volumetric flow rate for inductive liquids and pulps in the sealed pipes. The main application range can be found in the following fields: Petrol, chemical
Industry, power generation and distribution, mine, water treatment, paper industry, pharmaceutical industry, food and etc.
