Ball float alarm

A ball float alarm emits a signal when a liquid rises above a predetermined level inside a sump. The alarm is activated by conditions related to the rising and falling of the liquid in the cavity. The alarm emits a signal when the liquid rises above the predetermined level, and then powers off when the liquid falls beneath the predetermined level. A buoyant sphere is supported by a cable from above the cavity. The alarm floats on the liquid when the liquid level is above a predetermined level. When the sphere floats, the cable is lax. The lax cable causes a magnet and an alarm contact inside the alarm to pivotally join, and thus actuate an alarm signal. When the liquid falls below the predetermined level in the cavity, the cable becomes lax, causing the alarm contact to pivot distally from the magnet, which shuts off the alarm.

Liquid level and density measurement device

액체 수위 및 액체 밀도 측정 장치가 개시되어 있다. 액체 수위 및 액체 밀도 측정 장치에는, 연장 자기 변형 변환기 및 부표들 내에 내장되고 변환기를 따라 자유롭게 움직일 수 있는 2 이상의 변환기 자석이 있다. 하나의 부표는 나머지 다른 부표보다 액체 밀도 변화에 상대적으로 더 민감하다. 액체 수위 측정용으로 사용되는 부표가 덜 민감해 질수록, 액체 밀도 측정용으로 사용되는 부표는 더욱 민감해 진다. 액체 밀도 부표는 액체 내에 완전히 잠긴 하부 및 액체 내에 일부 잠긴 상부를 갖는다. 상부는 액체 수위 부표의 외경보다 큰 내경을 갖는 실질적으로 중공 실린더의 형태로 제조된다. 따라서, 액체 밀도 부표는 액체 수위 부표를 만지지 않고도 위아래로 움직일 수 있다. Apparatuses for measuring liquid level and liquid density are disclosed. In the liquid level and liquid density measuring device, there are two or more transducer magnets that are embedded in the extended magnetostrictive transducer and buoys and are free to move along the transducer. One buoy is relatively more sensitive to liquid density changes than the other buoys. The less sensitive the buoy used for measuring liquid level, the more sensitive the buoy used for measuring liquid density. The liquid density buoy has a lower part completely submerged in the liquid and an upper part partially submerged in the liquid. The top is made in the form of a substantially hollow cylinder having an inner diameter larger than the outer diameter of the liquid level buoy. Thus, the liquid density buoy can move up and down without touching the liquid level buoy.

DIGITAL OPTICAL OPTICAL MEASUREMENT SYSTEM OF A LIQUID LEVEL IN A CONTAINER BY CORRELATION OF SHOTS

LIQUID LEVEL SENSOR DEVICE

Washing machine water level control - by float with magnet in a differ-ential membrane valve unit

When the water level in a clothing or dish washing machine rises beyond its normal level, it flows into a float chamber causing a float to rise carrying a permanent magnet with it. The magnetic field is then insufficient to hold a ferrous valve which drops into its seating in the water flow chamber, blocking the outlet, the rapid rise in water press. causing membranes to seal the water channel. The purpose is to provide an accurate water level monitor, with rapid cut-off in the water input, in a system unaffected by dirt or corrosion.
