Type Of Flowmeters and Level gauges

All kinds of industrial flowmeters manufactured by GI Instruments of Canada can be presented in this section.
Liquid Turbine Flowmeter

These types of flowmeters are used for volume measurement or flow rate measurement. The principle of the work of these flowmeters is the same as a turbine. The rotation speed of the turbine rotor is proportional to the speed of the fluid flow that passes through the turbine. The rotation of the router around its axis induces an electromagnetic current around it, which is recorded by electrical sensors installed on the body of the flowmeter and converted into pulse signals or 4-20 milliamps. By having the fluid velocity and cross-sectional area, the device is able to display the volumetric flow rate.

Electromagnetic Flowmeter


The magnetic flowmeter is one of most flexible and universally applicable flow meter which does not have any moving parts and is ideal for waste water application or any dirty liquid which is conductive or water based. Magnetic flow meter is also ideal for the application where low pressure drop and low maintenance are required.

Technical Specification

- Fluid conductivity: 3µS/cm or great

- Accuracy: ±0.5% of rate & ±1.0% of rate

- Measurable velocity: ≤0.1 m/s

- Enclosure rating: JIS C 0920 Waterproof, NEMA TYPE4X, IEC lp66

- Hazardous area certification: FM approval for Division 2

- EMC conformity standards: En61326

- Adjust zero automatically

Coriolis Mass Flowmeter


The GICO Series Coriolis Meter is designed according to the principle of Coriolis force. Under the alternating current effect, the electromagnetic coils mounted on the measuring tube will make two parallel measuring tubes vibrating at a certain fixed frequency. Whenever mass (either liquid or gas) flows through the measuring tubes, Coriolis force is generated, causing a “bending” or “deflection” in the top of the tubes. This deflection is sensed as a phase shift between two electronic pick-ups mounted on the tubes. The degree of phase shift is directly proportional to the mass flow within the tubes. The mass flow rate can be calculated by detecting the phase shift of the tubes. The temperature is also measured and used for compensation.

Technical Specification

- Power consumption: ≤20W
- Enclosure rating: IP65, IP67, IP68 (Remote Style Options only)

Ultrasonic Flowmeter


Ultrasonic flow meters are the equipment of choice whenever the contact with the measured fluid isn't possible. Ultrasonic measurements are made by attaching two transducers onto the outside of a pipe. GIHU and GIWU series transit time ultrasonic flow meters measure the time difference between the ultrasonic pulse going upstream and the one propagating downstream. These sound waves are generated by a pair of transducers. The difference between the two intervals of time is a function of flow direction and velocity, and it represents an accurate measure for the average velocity of the liquid flowing through a pipe.

Technical Specification

- Flow range, ±0.03 ft/s ~ ±40 ft/s (±0.01 m/s~ ±12 m/s)
