GMT-H1 weighing transmitter is developed for managing incoming/outgoing material for silo weighing applications in concrete, asphalt mixing plants, feed, metallurgy and chemical batching industries.

In this video, we are going to demonstrate how to use GMT-H1 for silo weighing in managing in/out material weights.

Firstly, three important parameters need to be set, which are min in WT, min out WT, and in/out time delay. Entering the application settings, there is an IN/OUT materials setting page, which you can find these three parameters.

Here is an example, if it is the first time to set the parameters, we need to enter a six-digit password, the default password is 000000. Then enter the setting page, to set the minimum feed weight as 300g, and the minimum discharge weight is also set to 300g. Then we can set IN/OUT delay time to 1s, back to the home page. 

To verify if the setting parameter works, we put a 200g weight here, you can find there is no changes on GMT-H1, Likewise, we remove the weight, there is also no changes on display, as well as no signal for incoming and outgoing materials. That is because 200g is less than the minimum in/out weight we set. However when the 500g weight is placed on, we find that there is an in-feed symbol and the value is displayed after one second, and when the weight is removed,  the out-feed symbol is also displayed and the value is updated to the current WT after one second.

So the minimum IN/OUT weight means that when the material weight changes positively or negatively more than the set value, the weighing transmitter will consider that as a valid feeding or discharging action. The IN/OUT delay time provides that if the weight no longer changes within the set time, then the feeding or discharging is considered complete and the weight data is displayed.

GMT-H1 also offers a data recording function, which allows you to view one entry of data and daily weight data as well as the total accumulated data by entering the historical data page, which can also be accessed through the various communication protocols, like RS485,  Modbus-RTU, Modbus-TCP/IP, GPRS.
