Temperature Gauge and Flow Gauge in Water Heaters
Temperature is one of the most widely measured and controlled variable in any process. This is because there are several machines in which proper functioning and the required product is achieved only if the temperature is accurately measured and regulated. A Temperature gauge performs the important task of temperature measurement and monitoring. They function on the simple principle of thermal expansion or contraction of any element with a change in temperature and can be used to measure temperature of oil, water, flue-gas, etc.
An important household appliance in which temperature monitoring plays an important part is a water heater. In conventional water heaters, hot water is stored in a tank. Alternatively, "instant", tankless water heaters supply hot water immediately on demand. Unlike conventional water heaters, these do not have a tank in which water is stored and heated; they heat the water as it flows through the pipe.
Some of the important components of a water heater are: pipes to let the cold water in and hot water out, a thermostat to regulate the temperature, heating elements to heat the water and a pressure relief valve to keep the tank from exploding due to overpressure. Two of the most significant components that help in the making of any water heater are the temperature gauge and the flow gauge. As their names indicate, they measure the temperature and flow rates of water, respectively.
It is the thermostat that utilizes the temperature gauge, a temperature monitor. A specific temperature range is set, until which the water is to be heated. When the heater is switched on, the heating elements, along with the thermostat, get into action. When the lever on the thermostat is moved to turn up the heat, its in-built coil rotates. The resultant current starts heating the water. After it heats up to the desired limit, the temperature gauge signals the thermostat coil to unwind, thus breaking the circuit and turning off the heater.
Meanwhile, the flow gauge records and controls the flow and pressure of water. This is especially vital in instant water heaters. They function only when the faucet is turned on and water is flowing through the heater. The purpose of the flow gauge is to detect this flow and send a signal that turns on the heating element in the geyser. As soon as the outlet pipe is closed, the flow gauge signals the heating elements to turn off. Flow gauges also control the pressure that the water exerts on pipes by controlling the water flow.

what's the best combination of heat temperature and humidity for rice bread proofing in cabinet proofer?
i have bought proofer cabinet that has water reservoir and it has 2 controls outside the cabinet.They are for the water temperature & environment heat temperature. so, i want to know what are the best temperature for the water (as the source of humidity ) and the environment temperature in the cabinet should be set for proofing bread from blending of wheat & rice flour. i use straight dough method and need two times of proofing, before & after dough shaping.so, i need to know the combination of temperature for both proofing.
I hope this link will help you because it's an awful lot of information just to type here:
