Boiler steam drum two-color level gauge
Products overview:
ZW - B49H seriesBoiler steam drum two-color level gaugeIs after all the joint efforts of the scientific research personnel and further developed a new type of product, the luminous intensity is higher, further visual distance, scale label more clearly, the display area is big, product series;Liquid level display using high brightness LED double color light-emitting tube, level of red, green light shows, observation distance of 60 m during the day, night can reach above 200 m.Is installed on the boiler or other media for an instrument on the liquid container.
Second, the working principle:
ZW series - B49H boiler steam drum structure principle of two-color level gauge is a water level measurement equipment, installed on the boiler, direct observation water level.Two-color level meter through the optical principle of boiler water, steam, as suggested by the part are colored.Steam red, green water, steam red aqua green, steam full full red, full of green water, changing with water level automatic successive, is reliable monitoring of boiler water level, guarantee the safe operation of the boiler water level measurement.
Double color gauge connected to upper and lower valve, drain valve connected to the valve, the upper and lower valve flange connected to the boiler flange.In working status, the upper and lower valve is open (drain valve is closed at this time), so water level gauge and boiler constitute a connected circuits.The water level gauge of liquid level height is the water level in the boiler.
Applications:
ZW series - B49H boiler steam drum two-color level gauge equipped with limit switches, can realize the liquid level, the lower limit alarm and control;Equipped with liquid level transmitter, liquid level signal can be converted into 4 ~ 20 madc analog signal, realizing remote detection, indicating, recording, and control, also direct communication with the computer system.This series products are widely used in electric power, metallurgy, petroleum, chemical industry, environmental protection, shipbuilding, construction and other industries the production process, all kinds of tower, tank and boiler liquid level measurement and control of the equipment.

The installation location:
According to the installation position can be arbitrary change:
1, on the left side of the installation;
2, on the left side of the 600 installation;
3, standard installation;
4, the right side of the 600 installation;
5, the right side of the installation.
Seven, installation, use:
1, the hydraulic pressure meter flange and container seal on the flange clamp connection is good, screw down the bolt.
2, sensors, drain flange opening, in the float.Note: the float magnet steel end up, not the horse.
3, under the sensor drain flange, install a DN15 valve, with the original liquid level meter and drain pipe connected.
4, connect the power and input power AC36V insert AC220V power (or diameter), will the level to facilitate observation location.
5, open the valve on the first, and then slowly open the valve, especially the level meter used in high pressure, injection pressure ratio slowly, in case of float suddenly compression damage slowly into the sensor, make medium to observe the liquid level, according to the change from red to green one.
6, sewage, water, observe whether water level display, high and low water level alarm is normal, without abnormal phenomenon, can be put into use.
Eight, note:
1, form a complete set of instruments and accessories details see instruction corresponding instrument accessories.
2, in order to prevent lost or move far float up and down in the process of damage, with the level of correction magnetic steel factory supporting color logo (attached) will be on the outside of main pipe magnetic float.So after I receive my product or installation, please make correction magnets, so that float can move up and down with the liquid level, if the color is not consistent, before use available correction magnets which have suitable absorption, instrument can work normally.
3, level gauge after the installation, need correction magnets, the magnetic leads to a double column, so it shows zero the following red, zero or more display for the green.
4, level gauge according to user needs with heating jacket or electric heating device, such as user did not select this option when you order it, and after installation to using trace pipe road, and the mixed heating device of temperature should not exceed rated temperature of the liquid level gauge.
5, liquid level meter in travel, should first open the liquid pipe valves, and then, under the long open liquid pipe valve, let the liquid medium smoothly into the main pipe, avoid the liquid medium with float rise sharply, causing magnetic turn column flip failure or disorderly (if encounter the phenomenon, can use magnets to correction).
