Maid Labs Technologies Inc. products

The MerMaid hydraulic and electrical datalogger is a very small AC and battery powered datalogger that is able to monitor 3 phases for 3 motors, plus 4 digital inputs and one analog input. It reads every input 10 times per second. A reading is recorded only when its value has changed. This way for most lift stations it is possible to record one month of data before the newest data replaces the oldest. Each motor input can be used to record frequency, current or voltage. This device, which was created to do the best pump station diagnostic available is also perfect for preventive maintenance and troubleshooting electrical equipment. It can tell which motor, pump or equipment will fail next. It can find intermittent problems in minutes instead of hours or days without replacing parts. Compact in size this datalogger can be hidden in the electrical panel and work two weeks on 2C batteries.

Volucalc RT is a variable and constant speed pump flowmeter. For variable speed pumps, it uses the pump curves flow/head/RPM of 1 to 4 pumps, the level and pressure signal and generates a flow proportionnal 4-20mA output. It uses the most advanced patented volumetric flow algorithm for constant speed pumps. Data is downloaded to a USB key or MaidMaps. No software required to produce reports. MaidMaps can activate a remote relay and display readings.

Flow, real-time diagnostic, lower pump run time, cost reduction, increased safety. Abnormal behaviors are reported before degenerating to catastrophic events with real-time diagnostics using flow and efficiency monitoring. Pump run times, maintenance costs, and number and impact of SSO events decreases using our flow-based operating system. Volucalc Hybrid CS is a constant speed pump flow meter for 1 to 4 pumps with a flow proportional 4-20mA output and TCP/IP MODBUS communication. It uses the most advanced patented volumetric flow algorithm and is patent pending on its real-time volumetric flow algorithm. Its one second resolution data is downloaded to a USB key or MaidMaps SCADA. No software required to produce monthly reports with daily statistics.

The best sewer / wastewater pump station monitoring solution for up to 4 pumps. The best sewer / wastewater pump station monitoring solution for up to 4 pumps.

MaidMaps can activate a remote relay and display readings.

FlowMaid is a small open channel flow meter, which uses any level sensor to calculate flow from on a selection of 11 flow formulas. Each second, it records level, flow, volume and discrete events. Years of data can be recorded before filling its memory. Data can be downloaded through a USB key, WiFi, Internet or cellular modem. It automatically generates CSV reports of SSO events. The only requirement is to enter the level of the overflow pipe, its diameter, material, and angle. Every event shows start and end time, duration, average flow and volume lost, with daily totals. The relay outputs can be remotely activated or based on events such as high levels or extreme flow.

MLSD: Screwdriver with bits for Maid Labs small connectors.

MLCT75  Split-core current transformer is designed to provide a low cost method to monitoring electrical current. A unique hinge and locking snap allows attachment without interrupting the current-carrying wire. High secondary turn will develop signals up to 10.0 Vac across a burden resistor.

The current sensors MLCT150 (150 Amps) uses the latest current transformer technology. They are designed to meet the most stringent requirements in the industry. All models meet safety standards IEC1010-2-032, 600 V, Cat. II. These sensors have a jaw opening of 30 mm (1.19 ’’) and can accommodate a conductor with 29 mm (1.15 ’’). Its unique jaw facilitates fixing and hanging on the conductors. Manufactured in polycarbonate and welded by ultrasound in order to guarantee their robustness and their overall and lasting reliability. The use of coiled toroids improves high and low-end performance. The precision of each model is optimized for its current range. AC probes for frequencies from 40 Hz to 10 kHz.
