DESCRIPTION
The Monitor Model-M311 is durable manual controlled monitor for fixed installation as well as trailer mounted unit. The monitor is generally used for protection of flammable liquid storage tanks, loading racks, dykes marine and many other Industrial application. The monitor possess several design features that provides ease of operation, minimum maintenance and resistance to normally destructive environments. The monitor is used with aspirating, non-aspirating and water nozzles with flow range upto 800 gpm (3030 lpm). The monitor has welded carbon steel 3 inch (80 mm)
waterway. All steel parts are hot dip galvanized and epoxy painted for excellent corrosion resistant. The vertical and horizontal rotation is through corrosion resistant swiveling joints with double row of stainless steel ball bearing. Both vertical and horizontal movements are controlled by handle and twist lock.
MONITOR OPERATION
The monitor has large flow capability and can be manually operated by a single fire fighter. It is a fixed flow monitor and the flow is set as per client
requirement. The monitor design ensures to prevent jet reaction forces from effecting the horizontal and the vertical position of the monitor. The monitor has the ability for 360 deg.continuous horizontal rotation and angle of elevation +90 deg. above horizontal and –45 deg. below horizontal. The movement is made by holding the handle and position can be locked by setting the twist lockdown nuts. The water vanes in discharge tube reduces the
turbulence and friction loss, thus increasing the nozzle performance to achieve greater range. To ensure desired performance, the friction, loss through
monitor must be considered while selecting the nozzle and the flow through the monitor with reference to available base pressure at inlet of the monitor. The monitor‘s nozzle is of particular importance when using monitor for firefighting as it is the monitor nozzle that shapes the discharge jet. It has fog and jet angle which is user adjustable between wide fog and straight stream. The spinning teeth in the nozzle change the discharge pattern from jet to fog.
