M-Series Magnetic Level Gauge

Top Mounted

Description:

Application for chemical and petrol chemical process, boilers and other industries.

The M-Series magnetic level gauge consists of a chamber, magnetic float and strips.
The float rises or falls in the chamber, turning the indicative strips to provide a indication of the tank level.

M-Series also provides accessories such as switch and measuring sensors with a converter to turn 4-20mA (2 wires) DC output signal for liquid level control function.

Technical Data:

Connection: From 1/2” to 3” flange type, JIS, ANSI, DIN rating available; Special sizes available on request.
Center to Center Length: maximum 5500mm
Accuracy: ±4mm (Transmitter type: standard ±12mm; ±6mm on request)
Indicating Strips Material: Aluminum; Plastic (PBT) available
Colors are red and white
Specific Gravity: for standard type; 500-2900 kg/m3;
(for special type with high temp. <250°C, the Sp. Gr. must be 2800 kg/m3).
Indicating gauge orientation adjustable
Chamber Size: 50 or 60mm

Pressure Ratings:

70 PSI (5 kg/cm2) for Plastic chamber type (P.V.C, PP)
99 PSI (7 kg/cm2) for Plastic chamber type (PVDF)
284 PSI (20 kg/cm2) for Metal chamber type (Stainless Steel)
569 PSI (40 kg/cm2) for Metal chamber type (Stainless Steel) (Special request)

Temperature Ratings:

0 to 50°C for Plastic chamber type (P.V.C, PP);
-30 to 100°C for Plastic chamber type (PVDF);
-20 to 150°C for Metal chamber type (Stainless Steel)
-20 to 300°C for Metal chamber type (Stainless Steel) (Special request)
Note: If operating temperature exceeds 250°C, the Sp. Gr. must be greater than 0.8.

Please include the Specific Gravity and Viscocity of fluid when ordering.
